Jambmaths question: 

In the diagram above l1 is parallel to l2. Find the value of $\angle PMT$

Option A: 

82o

Option B: 

 36o

Option C: 

 72o

Option D: 

118o

Jamb Maths Solution: 

$\begin{align}  & \angle ABM=\angle BMD\text{    }\!\!\{\!\!\text{ Alternate angles} \\ & \angle BMD={{118}^{\circ }} \\ & {{(2y+10)}^{\circ }}+{{y}^{\circ }}={{118}^{\circ }} \\ & y=36 \\ & \angle PMT=2y+10={{[2(36)+10]}^{\circ }}={{82}^{\circ }} \\\end{align}$
