i really need pretty quick on this one. so plz hurry if u can.

The area of the shaded region is

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of the sector of circle of angle 68.9 degrees minus the area of the isosceles triangle

step 1

Find the area of sector of the circle

The area of circle is equal to

assume

substitute

Remember that the area of a circle subtends a central angle of 360 degrees

so

using proportion Find out the area of a sector with a central angle of 68.90 degrees

Let

x -----> the area of a sector

step 2

Find the area of the isosceles triangle

Applying the law of sines

The area is equal to

we have

substitute

step 3

Find the area of the shaded region

Round to the nearest tenth
