If m∠RST = (12x -1)°, m∠RSU = (9x -15)°,

and m∠UST = 53°, find the value of x.

• x = 22

• x = 3

• x = 13

• x = 8

Using the value that you found for x, figure out the measures of the angles.

• m∠RST = 155°

  m∠RSU = 102°

• m∠RST = 35°

  m∠RSU = 12°

• m∠RST = 263°

  m∠RSU = 183°

• m∠RST = 95°

  m∠RSU = 57°
