Question

the measures of the angles of a triangle are shown in the figure below. solve for x.

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°. So, we have the equation $50 + 72+x=180$.

Step2: Simplify the left - hand side

$50 + 72=122$, so the equation becomes $122 + x=180$.

Step3: Solve for x

Subtract 122 from both sides of the equation: $x=180 - 122$.
$x = 58$.

Answer:

58
