Question

Lines L and M are parallel, find M<7

Answer 1

142°

Explanation:

Lines L and M are parallel and a line is transversal to them.

`\therefore 38 \degree + m \angle7 = 180 \degree \\ (straight \: line \: \angle s) \\ \\ \therefore m \angle7 = 180 \degree - 38 \degree \\ \\ \huge \red { \boxed{\therefore m \angle7 = 142 \degree }}`
