Question

A triangle has an angle of 90 degrees and the other 2 angles are equal. What is the measurement of the other angles?

Answer 1

45 deg

Explanation:

let each of the other angles be x deg

it is given that the other 2 angles are equal, hence the 3 angles are 90 deg, x deg and x deg.

recall that the interior angles of a triangle always add up to 180 deg

hence,

90 + x + x = 180 deg

90 + 2x = 180

2x = 90

x = 45 deg
