And we are waiting to see the functions listed?
Answer:
The measure of the angles are 55° and 35°
Step-by-step explanation:
Sum of two angles that are complement of each other are 90.
The angles are A and B, so we can write:
A + B = 90
Also,
The difference is 20. Let A be the greater of them, so we can write equation 2 as:
A - B = 20
Now, we add up both equations, eliminate B and solve for A first:
A + B = 90
A - B = 20
---------------
2A = 90 + 20
2A = 110
A = 110/2
A = 55
And now the measure of B:
A + B = 90
55 + B = 90
B = 90 - 55
B = 35

Answer:
Step-by-step explanation:
Given:
Rosa has to skate around a face off circle five times.
Diameter of a circle = 9.0 m
Radius of a circle = 
Solution:
We know that the circumference of a circle.
Where;
r = Radius of a circle
Substitute 
in above equation.
So, the circumference of the circle is 28.26 m.
Rosa has to skate around a face off circle five times, so Rosa cover 28.26 m 5 times.
Therefore, the distance cover by Rosa to skate 141.3 m.
