Question

In the figure if Line l || m and the line n is the transversal then find the value of a and b

Answer 1

Given:$l\parallel m$

sum of the interior angles on the same side of transversal is ${180}^{\circ }$

$b+{52}^{\circ }={180}^{\circ }$

$\Rightarrow b={180}^{\circ }-{52}^{\circ }={128}^{\circ }$

And $a={52}^{\circ }$

$\therefore a={52}^{\circ },b={128}^{\circ }$
