Answer:
Step-by-step explanation:
The formula to find the area of a circle is
We know that
Therefore the area is
1) x=65
2) x= 70
3) x= 40
4) x= 131
5) x= 75
6) x= 49
7) x= -12
8) x= 42
∠P = 6x + 6
∠Q = 2x + 11
∠R = 2x + 3
∠P + ∠Q + ∠R = 180
(6x + 6) + (2x + 11) + (2x + 3) = 180
10x + 20 = 180
10x = 160
x = 16
∠Q = 2x + 11 = 2(16) + 11 = 32 + 11 = 43
Answer: 43°
