Question

find the value of x. triangle with angles 63°, 81°, and x°

Explanation:

Step1: Recall triangle angle sum

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

Step2: Set up the equation

$x + 63 + 81 = 180$

Step3: Calculate sum of known angles

$63 + 81 = 144$

Step4: Solve for $x$

$x = 180 - 144$

Answer:

$36$
