Simple Trig Question

[imported_itr]

i did this stuff last year but i'm reviewing some ACT questions and forgot how to solve this problem:

given angle A = 30 degrees and opposite leg= 6, find the hypotnuse.

do i use SIN or inverse of SIN? so far i have: SIN 30 (6/x)

this is quite embarrasing to have to post a simple math question.

Sin x = opposite/hypotenuse, so you'd want Sin 30 = 6/x and solve for x

Find the SIN of 30. Then cross multiply.

x=6/(sin 30)

i just remembered it's a 30, 60, 90 triangle, lol.
