Question

One angle of a triangle measures 136º. The other two angles are congruent.

Enter and solve an equation to find the measure x of the congruent angles.

Answer 1

22°

Explanation:

The sum of the 3 angles in a triangle = 180° , then

x + x + 136° = 180°

2x + 136° = 180° ( subtract 136° from both sides )

2x = 44° ( divide both sides by 2 )

x = 22°
