question
a side of the triangle below has been extended to form an exterior angle
find the value of $x$.
answer attempt 2 out of 2
$x = $

Explanation:

Step1: Find adjacent interior angle

The 156° angle is supplementary to the interior angle adjacent to it.
$180^\circ - 156^\circ = 24^\circ$

Step2: Use triangle angle sum property

The sum of angles in a triangle is $180^\circ$. Solve for $x$.
$x^\circ + 24^\circ + 49^\circ = 180^\circ$
$x = 180 - 24 - 49$

Answer:

$107$
