Question

One angle of a right triangle measures 45°. What is the measure of the other acute angle?

Answer 1

Below

Explanation:

EVERY triangle's angles add up to 180 degrees

a RIGHT triangle has a 90 degree angle

this right triangle also has a 45 degree angle

let x° = third angle

90° + 45° + x° = 180°

x = 180 - 90 - 45 = 45 degrees
