Question

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

Answer 1

x = 82°

Explanation:

The triangle sum theorem states that the sum (total measure) of all angles in a triangle must add up to 180°.

Therefore:

60° + 38° + x° = 180°

98° + x° = 180°

98° – 98° + x° = 180° – 98°

x = 82°
