Question

Given mC = 60° and mB = 30°. If BC = 12 cm, then find AC.

Answer 1

this is a 30-60-90 triangle which has sides with the ratio a-2a-a√3 where 2a is the hypotenuse, a is the short side and a√3 is the longer side (non hypotenuse).
In your problem 2a = 12 so the shorter side equals 12/2 or 6.

Answer 2

12 sqrt(3)

Answer 3

doh!!...hold on to that lol

Answer 4

AB would be 12√3 but AC is 6

Answer 5

6; I had my triangle backwards lol
