Question

One angle within a triangle is 76 degrees. What is the value of the exterior angle?

Answer 1

Answer:

The value of the exterior angle is $104\°$

Step-by-step explanation:

we know that

The sum of the interior angle plus the exterior angle is equal to $180\°$, because are supplementary angles.

Let

x-----> the measure of the exterior angle

so

$76\°+x=180\°$

solve for x

$x=180\°-76\°=104\°$
