Question

105° 36° $x^{circ}$ $x = square$

Explanation:

Step1: Recall angle - sum property of a triangle

The sum of the interior angles of a triangle is 180°. So, \(x + 105+36=180\).

Step2: Simplify the left - hand side of the equation

\(x + 141 = 180\).

Step3: Solve for \(x\)

Subtract 141 from both sides: \(x=180 - 141\).

Answer:
