Which equation would you use to find x?

• 3x + 4 + 8x + 16 = 130

• 3x + 4 + 130 = 8x + 16

• 8x + 16 + 130 = 3x + 4

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 is the correct equation to solve for x?

The sum of the measures of the angles of a trapezoid is 360 degrees. Write and solve an equation to find the measure of the missing angle.

• 290 + d = 360, d = 70

• 110 + d = 360, d = 250

• d + 80 = 360, d = 280

• d - 290 = 360, d = 650
