In the diagram above, l1 is parallel to l2, Find the value of < PMT...



Dicussion (1)

  • < MPT = \(180^{\circ}\) - \(118^{\circ}\) = \(62^{\circ}\)
    < PML = \(62^{\circ}\) (Alternating angles)
    y + 2y + \(10^{\circ}\) + \(62^{\circ}\) = \(180^{\circ}\) (Angles on a straight line)
    3y = 180 - 72
    \(\cfrac{3y}{3}\) = \(\cfrac{108}{3}\)
    y = \(36^{\circ}\)
    < PMT = 2y + 10 = 2(36) + 10 = \(82^{\circ}\)
