Question

value of x.

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°.

Step2: Set up an equation

We have \(45 + 76+x=180\).

Step3: Simplify the left - hand side

\(45 + 76=121\), so the equation becomes \(121 + x=180\).

Step4: Solve for x

Subtract 121 from both sides: \(x=180 - 121\).
\(x = 59\)

Answer:

59
