# 2. The two interior opposite angles of an exterior angle of a triangle are $\small 60^{\circ}$ and $\small 80^{\circ}$. Find the measure of the exterior angle.

P Pankaj Sanodiya

As we know that in a triangle, the exterior angle is equal to the sum of opposite interior angles.

So,

Exterior Angle =  $\small 60^{\circ}$$\small 80^{\circ}$.

= $140^0$

Hence the measure of the exterior is $140^0$.
