Make sure to complete all parts- A,B and C and show all the work the full credit create an equation and solve for X remember that supplementary angles added to 180°

Yep, angle 149° and another angle 13 X +5° what is X?
And we know that the angles is 149° your answer from a to find the missing angle measurement

A. Equation: 149° + (13X + 5°) = 180°

149 + 13X + 5 = 180
13X + 154 = 180
13X = 26
X = 2

B. The missing angle measurement is:
13(2) + 5 = 26 + 5 = 31°

C. The two angles are supplementary because they add up to 180°.
