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

Explanation:

Step1: Find adjacent interior angle

The 156° angle and the interior angle adjacent to it form a straight line (180°).
$180^\circ - 156^\circ = 24^\circ$

Step2: Use triangle angle sum property

The sum of angles in a triangle is 180°. Let the unknown angle be $x$.
$x + 24^\circ + 49^\circ = 180^\circ$

Step3: Solve for $x$

Calculate the sum of known angles, then subtract from 180°.
$x = 180^\circ - (24^\circ + 49^\circ) = 180^\circ - 73^\circ = 107^\circ$

Answer:

$107$
