Question

The smallest angle of a right triangle is 20-degree angle. What is the measure of the medium angle?

Answer 1

70 degrees.

Explanation:

Hello!

It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.

90 + 20 = 110

180 - 110 = 70.

So the medium angle is 70°.

Hope this helps!
