Question

Find the length of the longer leg of a 30°-60°-90° triangle with a hypotenuse of 6 in.

Answer 1

Alright, so we know that the longer leg will be across from the larger angle. Using that, we can assemble the triangle and decide which trig function we'd like to use to get the length.

Let's choose the larger angle of 60 to use. Do you know which trig function relates the opposite angle and the hypotenuse?
