Mathematics

If $$l\parallel m$$ and $$p\parallel q$$, find $$a,b,c,d$$.


SOLUTION
$$a + {57^o} = {180^o}$$
$$a = {180^o} - {57^o}$$
$$a = {123^o}$$
$$a + b = {180^o}$$ ........ (Co-interior angles)
$${123^o} + b = {180^o}$$
$$b = {180^o} - {123^o}$$
$$b = {57^o}$$
$$c = a$$ ........ (corresponding angle)
$$ = {123^o}$$
$$d = c = {123^o}$$ ......... (vertically opposite angles)
