TS is an angle bisector. If m∠RTS=x+10 and m∠UTS=2x+5, find m∠RTU. answer choices below

30°30 degrees

15°15 degrees

80°80 degrees

5°

m∠RTS= 15°, m∠UTS= 15°, m∠RTU= 30°

Step-by-step explanation:

Since TS bisects RTS and UTS, that means the two angles are equal to each other. So let's find x first.

x+10=2x+5, subtract x to both sides

10=x+5, subtract 5 to both sides

x=5

Since RTU is basically RTS plus UTS, let's add the two angles together

x+10+2x+5, combine like terms

3x+15

Then we can plug in 5 for x

3(5)+15

15+15

=30

So, RTU is 30 degrees
