In triangle a b c, angle c is a right angle and bc = 11. if lower m angle b equals 30 degrees, find ac.

 or  

Step-by-step explanation:

we know that

In the right triangle ABC

AC and BC are the legs of the triangle

AB is the hypotenuse

see the attached figure to better understand the problem

so

substitute the value of BC

step-by-step explanation:
