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

Explanation:

Step1: Find adjacent interior angle

The 156° angle and its adjacent interior angle are supplementary (form a straight line).
$180^\circ - 156^\circ = 24^\circ$

Step2: Use triangle angle sum property

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

Answer:

$107$
