  • 8x + 4x =180
    12x = 180
    x = 180/12
    x= 15

  • SPQ = RSP = 90 derajat.

    Total sudut trapesium 360 drjt

    SPQ + RSP + SRQ + RQP = 360
    90 + 90 + 8x + 4x = 360
    180 + 12x = 360
    12x = 360 - 180
    12x = 180
    x = 180/12
    x = 15

    SRQ = 8x = 8(15) = 120 drjt
    RQP = 4x = 4(15) = 60 drjt
