Question

Find x and y.

A) x = 30√3, y = 30

B) x = 15√3, y = 15

C) x = 15, y = 15√3

D) x = 30, y = 30√3

Answer 1

C, because the rule for a 30/60/90 triangle if the hypotenuse (the side opposite the 90 degree angle) is 2X, the side opposite the 30 degree angle is X, and the one opposite the 60 degree angle is X times square root of 3 and so if x is opposite the 30 degree, it’ll be y divided by square root of 3. hope this helped!
