The measure of angle 1, m∠1, found using the congruency of the angles and the angle sum property of a triangle is 55°
What is the angle sum property of a triangle?The angle sum property of a triangle specifies that the sum of the interior angles of a triangle is 180°
Please find attached the presentation of the details of the question as a drawing of the triangles created with MS Word
The parameters of the question are;
The number of arcs on angles b and q = Single arcs
Therefore, based on the arc markings indicating congruency of the angles, we get;
Angle b is congruent to angle q ∠b ≅ ∠q
Therefore, ∠b = ∠q, by the definition of congruency
The number of arcs on angle a and angle s = Double arcs
Therefore, angle a is congruent to angle s based on the arc markings, which indicates;
∠a ≅ ∠s
∠a = ∠s by the definition of congruency
The label on angle ∠a = 45°
The label on angle ∠b = 80°
∠a = ∠s, therefore, ∠s = 45°, by substitution property
∠b = ∠q, therefore, ∠q = 80° by substitution
∠s + ∠q + ∠1 = 180° Angle sum property of a triangle
45° + 80° + m∠1 = 180°
m∠1 = 180° - (45° + 80°) = 55°

Here is my question :
I need help with finding the vertex,range and domain interval
THis is the graph of a positive parabola, that opens upward.
The equation is:
\(y=x^2+2x-3\)The general form of a quadratic is >>>
\(ax^2+bx+c\)So,
a = 1
b = 2
c = -3
(a)The vertex is the lowest point of the parabola. The x-coordinate is:
\(\begin{gathered} x=-\frac{b}{2a} \\ x=-\frac{2}{2(1)} \\ x=-1 \end{gathered}\)And y is:
\(\begin{gathered} y=x^2+2x-3 \\ y=(-1)^2+2(-1)-3 \\ y=1-2-3 \\ y=-4 \end{gathered}\)The vertex is at (-1, -4).
(b)The range is the set of y-values for which a function is defined. From the graph, we can see that the parabola is defined from y = -4 to y = 0. In interval notation >>>
\(\text{Range}=\lbrack-4,0\rbrack\)(c)The domain is the set of x-values for which a function is defined.
The two x-axis points are the x-intercepts. They are found below:
\(\begin{gathered} y=x^2+2x-3 \\ y=(x+3)(x-1) \\ 0=(x+3)(x-1) \\ x=-3,1 \end{gathered}\)From the graph, we can see that the parabola is defined from x = -3 (not included point) until x = 1. So, the domain is >>>

A. The function must be a straight line. The function must be a straight line.
B. The function must pass the vertical line test. The function must pass the vertical line test.
C. The inverse relation must be a straight line. The inverse relation must be a straight line.
D. The inverse relation must pass the vertical line test.
the correct option is D:
" The inverse relation must pass the vertical line test."
Which is one condition that must be present for an inverse relation to be a function?
Remember that a relation is only a function if each value in the domain is only mapped into a single value in the range.
All functions need to pass what is called the "vertical line test" this means that if you draw a vertical line on the graph of the function, the vertical line can intersect the graph at most one time. If the vertical line intercepts the graph two or more times, then it is not a function.
From this we conclude that the correct option is D:
" The inverse relation must pass the vertical line test."

The diameter of a bicycle wheel is 60 centimeters. How far does the wheel travel when it makes 35 revolutions? Give your answer in. meters( Math in focus singapore math course 1 B)
Answer:
The circumference of a circle is given by the formula "C = pi x d" where "d" is the diameter and "pi" is the mathematical constant with an approximate value of 3.14.
In this problem, the diameter of the bicycle wheel is 60 centimeters, so its circumference is:
C = pi x d = 3.14 x 60 = 188.4 centimeters
When the wheel makes one revolution, it travels one circumference distance. Therefore, when the wheel makes 35 revolutions, it will travel:
distance = 35 x circumference = 35 x 188.4 = 6584 centimeters
We can convert centimeters to meters by dividing the distance by 100:
distance = 6584 ÷ 100 = 65.84 meters
Therefore, the wheel travels 65.84 meters when it makes 35 revolutions.

The number of sets of numbers that have a sum of 32are; 5 sets
A combination is the possible ways in which a number of items can be arranged, and in which the order in which the items are arranged is not taken into account.
The set of natural numbers are the numbers, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10
Testing sets of seven randomly selected numbers indicates;
1 + 2 + 3 + 4 + 5 + 6 + 7 = 28
The above numbers can be made to be equivalent to 32 by the addition of 4 as follows;
Increasing the values of the sum of the numbers by 4, we get;
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 4 + 5 + 6 + 11 = 32
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 4 + 5 + 10 + 7 = 32
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 4 + 9 + 6 + 7 = 32
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 8 + 5 + 6 + 7 = 32
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 4 + 5 + 8 + 9 = 32
1 + 2 + 3 + 4 + 5 + 6 + 7 + 4 = 1 + 2 + 3 + 5 + 8 + 6 + 7 = 32

29.For n ≥ 3, a pattern can be made by overlapping n circles, each of circumference 1 unit, so that each circle passes through a central point and the resulting pattern has order-n rotational symmetry.
For instance, the diagram shows the pattern where n = 7.
If the total length of visible ares is 60 units, what is n?
The value of n can be determined by finding the number of visible arcs in the pattern, which is 30 in this case.
To determine the value of n, we need to find the relationship between the total length of visible areas and the number of circles (n).
In the given pattern, each circle contributes to the visible area twice: once as its circumference and once as the overlapping part with the adjacent circles. Since the circumference of each circle is 1 unit, the visible area contributed by each circle is 2 units.
Therefore, the total length of visible areas can be expressed as 2n. Given that the total length is 60 units, we can set up the equation:
2n = 60
Solving this equation, we find:
n = 60/2 = 30
Thus, the value of n is 30.

Then 62.5% of the campers at the Wild Outdoors camp this morning will be horseback riding
To find the percentage of campers that will be horseback riding, we need to first add the ratio together to get the total number of parts. In this case, the ratio of horseback riding to canoeing is 5:3, so there are 5 + 3 = 8 parts in total.
To find the percentage of campers that will be horseback riding, we divide the number of parts for horseback riding by the total number of parts, then multiply by 100 to get the percentage.
So, 5 parts out of 8 parts are for horseback riding. This is equivalent to 5/8 or 0.625 as a decimal. To find the percentage, we multiply by 100, which gives us 62.5%.
