Answer:
idk of u can understand that but the answer is 2125
The area of a circle is pi * radius squared, thus the area of the circle is 64(pi). Since we have a sector with 90 degree angle, the area of the sector is exactly 1/4 the area of the entire circle, or 16(pi)
-16+x=-15
here we have to isolate x, so adding 16 to both sides
x=-15+16
x=1
Answer: 75°
