Question

Find the value of $\angle n$ , if line 'bc' is parallel to 'ad' and line 'l' is a transversal.

• A. ${110}^{\circ }$
• B. ${90}^{\circ }$
• C. ${70}^{\circ }$
• D. ${100}^{\circ }$

Answer 1

The correct option is A ${110}^{\circ }$

In the above figure
line 'bc' is parallel to line 'ad' and line 'l' is a transversal.
Than $\angle n=\angle m$ [Corresponding Angle]
$\angle m={110}^{\circ }$
$\therefore$ $\angle n={110}^{\circ }$
