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

Answer:
the unknown side of triangle is 15 in :)
213 divided by 7 equals 30.43
Evaluate all the absolute value first.
|-7|=7
|4|=4
Rewrite and solve using the order of operations
7+3*4
7+12
19
Final answer: 19
