Question

The measures of the angles of a triangle are shown in the figure below. Solve for x. 60° ​

Answer 1

x = 30

Explanation:

the sum of the 3 angles in a triangle = 180°

sum the 3 angles and equate to 180°

x + 90° + 60° = 180° , that is

x + 150° = 180° ( subtract 150° from both sides )

x = 30°
