Answer
c,116°
Step-by-step explanation:
i don't know how to draw a diagram?
Join ends of chord with the center making angles ∠2,∠3 and angle at the center.
angle at the center=128°
∠1=∠2+90°
∠2=∠3
∠2+∠3+128=180
∠2+∠2+128=180
2∠2=180-128=52
∠2=52/2=26
∠1=26+90=116°
sorry i can't explain properly without picure.
-3(x+5)=-9
-3x-15=-9

-1x=2
1x=-2
x=-2
I believe the answer is AD=7.0
Most of the time it will be Length x Width x Height.
