Question

find the value of x.

Explanation:

Step1: Recall triangle angle sum rule

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

Step2: Set up the equation

$57 + 82 + x = 180$

Step3: Calculate sum of known angles

$57 + 82 = 139$

Step4: Solve for $x$

$x = 180 - 139$

Answer:

$41$
