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

Given m∠QST = 135°, find the value of x.

• x = 26

• x = 28

• x = 27

• x = 29

If m∠RST = (12x -1)°, m∠RSU = (9x -15)°,
and m∠UST = 53°, find each measure.

• x = 13

  m∠RST = 155°

  m∠RSU = 102°

• x = 3

  m∠RST = 35°

  m∠RSU = 12°

• x = 22

  m∠RST = 263°

  m∠RSU = 183°

• x = 8

  m∠RST = 95°

  m∠RSU = 57°

• x = 5

• x = 11

• x = 33

• x = 5°

Solve

• x = 6

• x = 7

• x = 12

• x = 144

Solve for x (you don't need to find the two angles unless you want to check your answer.)
