Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, 46°+88°+x° = 180°.

Step2: Simplify the left - hand side

46 + 88+x=180, which gives 134 + x=180.

Step3: Solve for x

Subtract 134 from both sides: x=180 - 134.
x = 46.

Answer:

46
