Question

In the given figure, the straight line AB and CD are parallel to each other. If angle $p={55}^0$ and $q={43}^0$then answer the given question.Find the value of r.

• A. ${55}^0$
• B. ${82}^0$
• C. ${108}^0$
• D. ${43}^0$

Answer 1

The correct option is B ${82}^0$

We know that,

$\Rightarrow$$\angle P+\angle q+\angle r=180°$ (Linear pair)

So, $\angle r=180°-55°-43°=82°$
