Question

the measures of the angles of a triangle are shown in the figure below. solve for x. answer attempt 1 out of 1 x =

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°. So, we have the equation $43 + 72+x=180$.

Step2: Simplify the left - hand side

$43 + 72=115$, so the equation becomes $115 + x=180$.

Step3: Solve for x

Subtract 115 from both sides of the equation: $x=180 - 115$.
$x = 65$.

Answer:

$65$
