Answer:
144°
Step-by-step explanation:
First, find the area of the circle, with the formula A =
r²
Plug in 10 as the radius, and solve
A =
r²
A =
(10²)
A = 100
Using this, create a proportion that relates the area of the sector to the degree measure of the arc.
Let x represent the degree measure of the arc of the sector:
= 
Cross multiply and solve for x:
100
x = 14400
x = 144
So, the degree measure of the sector arc is 144°
They are both found by adding all the sides
Answer:
A: 3:5
B: Yes because 3 plus two is five
Basically all you have to do is to find what the question is telling you and the unit you will get it from the question example: 15 is what percent of 90 so first work out the question then the unit is percent% because they say what percent.
hope i helped
