Answer:
x = 16
Step-by-step explanation:
Using the cosine ratio in the right triangle and the exact value
cos60° = 
cos60° =
= 
Multiply both sides by x
x × cos60° = 8, that is
x ×
= 8
Multiply both sides by 2
x = 16
A is the answer I hope e2020 is going good for you
Area of the sector = 1/2 * r^2 * theta where theta is the angle subtended by the arc at the center ( in radians)
In this case m < theta = 360 - 235 = 125 degrees or 2.182 radians
So, the area of shaded area = 1/2 * 20^2 * 2.182 = 436.4 in^2
Answer:
28.28(simplified from 28.2743338834)
Step-by-step explanation:
area of sector= (center angle/360)*area of circle
we are already given the area of sector as 3/2pi
so
3/2pi=(60/360)*x
(x is area of circle)
3/2pi=4.71238898038
4.71238898038=1/6x
divide both sides by "1/6"
28.2743338834=x
hope this helps!
