Area of sector = 1/2 * r^2 * x where r = radius and x = angle in radians
86 = 1/2 * r^2 * pi/4
r^2 = 2 * 86 * 4 / pi = 219
r = sqrt 219
= 14.80
Answer: The answer is A, 132 units
Step-by-step explanation:
Answer:
200
Step-by-step explanation:
The nearest ten for 155 would be 200
I think this is right
-11 > 55
You divide both sides by -11
Step-by-step explanation:
- blue one ====> 3x+16 =9x+4 ( alternate angles)
>9x-3x=16-4
>6x=12
>x=2.
- white one ====> 10x-2=9x+5 (corresponding angle)
>10x-9x=5+2
>x=7.
- green one ====>8x+10=6x+30(vertically opposite angle)
>8x-6x=30-10
>2x=20
>x=10.
hope this helps you.
