Question

the measures of the angles of a triangle are shown in the figure below. solve for x. answer attempt 1 out of 2 x =

Explanation:

Step1: Recall angle - sum property

The sum of the interior angles of a triangle is 180°. So, $55 + 76+x=180$.

Step2: Simplify the left - hand side

$55 + 76=131$, so the equation becomes $131 + x=180$.

Step3: Solve for x

Subtract 131 from both sides: $x=180 - 131$.
$x = 49$.

Answer:

49
