In parallelogram TRIG, m∠R = 2x + 19 and m∠G = 4x - 17.
What is m∠T

  • geometry -

    Opposite angles in a parallelogram are equal, assuming you are following the convention of listing vertices in order, then
    4x-17 = 2x+19
    2x = 36
    x = 18
    so angle R = 55°
    then angle T = 180-55 = 125°
