Question

Two angles are supplementary. One measures (3x) degrees and the other measures 51 degrees.

a. Write an equation to show the relationship between the two angles and solve for the value of x.

b. Find the measure of both angles

Answer 1

a. 3x +51=180

x=43

b. 3(43)+51 =180 51 degrees; 129 degrees

Explanation:

3x +51 =180

3x=180-51

3x=129

x=43
