3^3 = 27, so 3 is a good value.

(-3)^3 = -27, not it's not -3

9^3 = 729, so 9 is not good.

(-9)^3 = -729, so -9 is not good.

The answer is A) x=3.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
