Question

In Triangle ABC, angle C is a right angle and BC=11 if the measure of angle b is 30 degrees, Find AC. I need help with the whole Precalc B final please help me!

Answer 1

Th angle for AC equals 60 because a right angle is 90 and the angle for b is 30 and a triangle has to add up to 180 so 180-120(90+30)=60
