Question 4 (i)
Find the values of x in each of the following figures if l || m

Answer 1

$\text{Given l, m and t is the transversal line.}\therefore \text{Interior vertically opposite angle between lines l and t = 110.}\therefore {110}^{\circ }+x={180}^{\circ }\text{[Supplementary angles]}x={180}^{\circ }-{110}^{\circ }={70}^{\circ }$
