Question

A right triangle has one angle that measures 40°. What is the measure of the other acute angle?

Answer 1

50º

Explanation:

Since all angles of a triangle have a sum of 180º, we can add 90º (since it's a right triangle) and 40º. This gives us 130º, which we can then subtract from the 180º total. The answer is then 50º.

Answer 2

50

Explanation:

a right triangle is 90 degrees so if one angle is 40 the other has to be 50.
