Use pi•r^2 for the formula of a circle. filling it in, you get 3.14•64 which is 200.96
A=x
B= 2x
C=3x
If you add them up =
6x =180
÷6 both sides
x=30
A=30
B=60
C=90
one angle is 90 degrees so the triangle is classified as a right triangle
Answer:
so 2x+3x+130=180
so 5x+130=180
5x=50
so 2x =20
3x which is angle a is equal to 30 degree
Answer:
11 17/21
