Answer:

Step-by-step explanation:
we know that
The area of the shaded region is equal to the area of the sector minus the area of the triangle
step 1
Find the area of the circle
the area of the circle is equal to

we have

substitute


step 2
Find the area of the sector
we know that
The area of the circle subtends a central angle of 360 degrees
so
by proportion find out the area of a sector by a central angle of 72 degrees

step 3
Find the area of triangle
The area of the triangle is equal to

step 4
Find the area of the shaded region
Subtract the area of the triangle from the area of the sector

we are given

we can also write it as

now, we can use factor formula

we can use above formula
we get

now, we can simplify it

now, we can set it to 0

and then we can solve for x




now, we can use quadratic formula

now, we can plug values
and we get


So, we will get solution as
