angle rst is a right angle. angle rsu has a measure of 25°. what is the measure of angle tsu? 25° 45° 65° 75°

Explanation:

Step1: Recall angle - addition property

We know that $\angle RST=\angle RSU+\angle TSU$, and $\angle RST = 90^{\circ}$, $\angle RSU=25^{\circ}$.

Step2: Solve for $\angle TSU$

$\angle TSU=\angle RST-\angle RSU$. Substitute the values: $\angle TSU = 90^{\circ}-25^{\circ}$. $90 - 25=65$.

Answer:

$65^{\circ}$
