Angelina_Jolie [31]

Keywords

complementary angles, right angle

we know that

If two angles are <u>complementary angles</u>, then their sum is equal to a <u>right angle</u>

In this problem

$Angle\ RSU+Angle\ TSU=90\°$ -------> by <u>complementary angles</u>

we have

$Angle\ RSU=25\°$

Substitute and solve for Angle TSU

$Angle\ TSU=90\°-25\°=65\°$

therefore

the answer is the option

$65\°$
