Question

find the value of x.
triangle with angles 38°, 76°, and x°

Explanation:

Step1: Recall triangle angle sum

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

Step2: Set up the equation

$x + 38 + 76 = 180$

Step3: Calculate known angle sum

$38 + 76 = 114$

Step4: Solve for $x$

$x = 180 - 114$

Answer:

$66$
