Answer:

  • Sum of interior angles of a quadrilateral is 360°

Find x first:

  • m∠A + m∠B + m∠C + m∠D = 360°
  • 8x - 65 + 6x - 53 + x + 121 + 6x + 21 = 360
  • 21x + 24 = 360
  • 21x = 336
  • x = 336/21
  • x = 16

Find angle measures:

  • m∠A = 8*16 - 65 = 63°
  • m∠B = 6*16 - 53 = 43°
  • m∠C = 16 + 121 = 137°
  • m∠D = 6*16 + 21 = 117°

Each angle has a different measure, it means the sides are all different.

The quadrilateral ABCD is likely a trapezoid.
