The measure of all the angles for a triangle is 180°. To find the other two angles, you must subtract 90 from 180 and you get 90° then you divide 90° by 2 and you get 45°.

You have two 45° angles and one 90° angle

Answer:

Sample Explanation: The sum of the measure of the interior angles of a triangle is 180°. If x represents the measure of one of the congruent interior angles, then 2x + 90 =180 represents the sum of the measures of all the angles. Solve the equation and x = 45°.
