Question

in the diagram, $angle trv cong angle vrw$.
what is the measure of $angle srt$
$mangle srt = square$ degrees

Explanation:

Step1: Identify straight angle property

$\angle TRW = 180^\circ$ (straight angle)

Step2: Use congruent angles

Since $\angle TRV \cong \angle VRW$, $\angle TRV = \angle VRW = \frac{180^\circ}{2} = 90^\circ$

Step3: Identify vertical angles

$\angle SRT$ and $\angle VRW$ are vertical angles, so $\angle SRT = \angle VRW$

Answer:

90 degrees
