Answer explanation

1) Set up your equation by knowing it is a supplementary relationship

x+3+49=180

2) Combine like terms

x+52=180

3) Solve by subtracting 52 from both sides

x=128

Tell whether the angles are complementary or supplementary. Then find the value of x.

• Complementary; x=25

• Complementary; x=5

• Supplementary; x=25

• Supplementary; x=5
