Question

find the value of x.

Explanation:

Step1: Recall triangle angle sum

The sum of angles in a triangle is $180^\circ$.

Step2: Set up the equation

$72^\circ + 76^\circ + x^\circ = 180^\circ$

Step3: Calculate sum of known angles

$72 + 76 = 148$

Step4: Solve for $x$

$x = 180 - 148$

Answer:

$32$
