Question

In a right triangle ABC angle B is the right angle and m angle C = 30 degrees if AC = 10 what is AB

Answer 1

• AB = 5

Explanation:

This is a 30°-60°-90° right triangle.

AC is hypotenuse, AB is opposite side to 30° angle.

We know that in such a triangle the side opposite to 30° angle is half the hypotenuse.

So we have:

• AB = 1/2AC = 1/2(10) = 5
