80+58 = 138

180 - 138 = 42

42+x = 180

x = 180-42 = 138

Answer:

138

Explanation:

x is an exterior angle of a triangle.

If you didn't know, an exterior angle of a triangle is equal to the sum of its opposite interior angles.

The opposite interior angles of x have measures of 80 degrees and 58 degrees.

Hence, x = 80 + 58 = 138
