Question

solve for m∠stv.
answer
m∠stv =

Explanation:

Step1: Observe angle relationships

We know that the larger angle formed by rays $ST$ and $UV$ is $105^{\circ}$ and the smaller angle $\angle UTV = 48^{\circ}$.

Step2: Calculate $\angle STV$

Since $\angle STV=\text{the larger angle}-\angle UTV$, we have $m\angle STV = 105^{\circ}- 48^{\circ}$.
$m\angle STV=57^{\circ}$

Answer:

$57$
