Answer:

x = 55

Step-by-step explanation:

A triangle equals 180 degrees, b will be used to find the missing angle.

21 + 34 + b = 180

55 + b = 180

subtract 55 from both sides

b = 125

A straight line is 180 degrees and the b, the missing angle, and x are supplementary angles so

125 + x = 180

x = 55
