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, \(80 + 57+x=180\).

Step2: Simplify the left - hand side

\(137 + x=180\).

Step3: Solve for x

Subtract 137 from both sides: \(x=180 - 137\).
