x = ?

• 5

• 15

• 12

• 10

Answer explanation

Start by solving for x.

Since all three angles lie on a straight line, the three angles must add up to 180.

We can then write the following equation to solve for x.

6x−10+4x+6+7x+14=180

Combine Like Terms

17x+10=180

17x=180-10

17x=170

x=170/17

x=10

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°
