Question

find unknown lettered angle​

Answer 1

Answer:

x = 18°

3x= 54°

2x = 36°

Step-by-step explanation:

Sum of all angles of a triangle = 180°

Measure of the angle given = 90°

Measure of the remaining angles = 180° - 90° = 90°

3x + 2x = 5x

5x = 90°

x = 90° ÷ 5 = 18°

2x = 18° x 2 = 36°

3x = 18° x 3 = 54°
