Question

the interior opposite angle is 50 degrees what will be the exterior angle

Answer 1

Answer:

The measure of exterior angle is $130^{0}$.

Step-by-step explanation:

Given : The interior opposite angle = $50^{0}$

To find : Exterior angle = ?

Solution :

• It is given that the interior opposite angle = $50^{0}$
• We have to find the exterior angle.
• As we know that "When two parallel lines are intersected by a third line, then the angles made inside the parallel lines on the same side of third line, that angles are known as interior opposite angle."
• Now,

       Interior angle + Exterior angle = $180^{0}$

              ∴  $50^{0}$ + Exterior angle = $180^{0}$

                         ∴  Exterior angle = $180^{0} -50^{0}$

                          ∴   Exterior angle = $130^{0}$

• ∴ The measure of exterior angle is $130^{0}$.
