Set up an equation that will help you solve for x.

• 60 + 75 + 180 = x

• 60 + 75 + x = 180

• 60 + 75 = x

• 60 + x = 75

• x = 5

• x = 11

• x = 33

• x = 5°

What equation should you use to find the value of x if the measure of angle PQS is 165?

• 165+40=5x

• 5x+40=165

• 5x-40=165

• 5x+165=40

Find x.

• 0.3

• 3

• 7

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°

Which equation would you use to find x?

• 12x - 8 + 136 = 4x

• 12x - 8 + 4x = 136

• 4x + 136 = 12x - 8

The measure of angle 1 is 60 degrees. What is the measure of angle 5?
