Question

question find m∠str. answer attempt 1 out of 2 m∠str = ° submit answer

Explanation:

Step1: Identify triangle type

The triangle has two equal - side markings, so it is isosceles. In an isosceles triangle, the base - angles are equal. Let $\angle STR=\angle SRT = x$.

Step2: Use angle - sum property of a triangle

The sum of the interior angles of a triangle is $180^{\circ}$. So, $68^{\circ}+x + x=180^{\circ}$.

Step3: Solve the equation

Combine like - terms: $68^{\circ}+2x = 180^{\circ}$. Subtract $68^{\circ}$ from both sides: $2x=180^{\circ}-68^{\circ}=112^{\circ}$. Then divide both sides by 2: $x=\frac{112^{\circ}}{2}=56^{\circ}$.

Answer:

$56$
