Question

In the figure given below,

Find the value of

$\angle 1+\angle 2$.

• A. 180°
• B. 270°
• C. 190°
• D. Insufficient Data

Answer 1

The correct option is C

190°

$\angle 1$ and ${72}^{\circ }$ & $\angle 2$ and ${98}^{\circ }$ forms two pairs of linear pair of angles.

We know that the sum of a linear pair of angles is ${180}^{\circ }$.

Therefore,

$\angle 1={108}^{\circ }$

$\angle 2={82}^{\circ }$

$\angle 1+\angle 2={190}^{\circ }$
