Question

One angle of a triangle measures 122 degrees. The other two angles are congruent. Enter and solve an equation to find the measure of the congruent angles

Answer 1

29 degrees

Explanation:

Let the measure of each of the two congruent angles be x.

The sum of the measures of the angles of a triangle is 180 degrees.

x + x + 122 = 180

2x + 122 = 180

2x = 58

x = 29

Answer: 29 degrees
