Question

In triangle JKL, if J = 60° and K = 40°, then find the value of exterior angle formed by
extending the side KL.​

Answer 1

The exterior angle formed by extending the side KL is 100°.

Step-by-step explanation:

Given:

A triangle JKL with $\angle J=60\°$ and $\angle K=40\°$

Now, the triangle is shown below.

From the exterior angle theorem for a triangle, the exterior angle of a triangle is equal to the sum of the opposite interior angles. Therefore,

$\angle JLM=\angle J + \angle K\\\angle JLM=60+40=100\°$

Therefore, the exterior angle formed by extending the side KL is 100°
