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

Explanation

< MPT = 180^o - 118^o = 62^o

< PML = 62^o ( Alternative angle)

y + 2y + 10^o + 62^o = 180^o (Angles on a straight line)

3y = 180 - 72
\(\frac{3y}{3}\) = \(\frac{108}{3}\)
y = 36^o

< PMT = 2y + 10 = 2(36) + 10 = 82^o

There is an explanation video available .
