Question

find the 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 106° + 34°+x° = 180°.

Step3: Simplify the left - hand side

106 + 34+x=180, 140 + x=180.

Step4: Solve for x

Subtract 140 from both sides: x = 180 - 140.

Answer:
