well if you equation is 1/2x=21 then you answer would be x=21
because if you make 1/2 a decimal it is 0.5 and you want to have x alone so you would divide 1/2 by 0.5 and then you would have 1x=21 which is x=21

b) Arc AN =
Answer:
a. x = 36
b. ∠(AN) = 144°
Step-by-step explanation:
All the angle in the circle should add up to 360°.
x + x + 4x + 4x = 360
2x + 8x = 360
10x = 360
x = 36
∠(AN) = 4x
∠(AN) = 4(36)
∠(AN) = 144°
