Answer: 110 degrees

Step-by-step explanation:

We know that RU and angle 1 makes an 180 angle. So 180 - 70 = 110. So as a result, 110 degrees is the answer.

Hope this helps!

Answer:

Let O is intersection of RS and TU

As property of angle on circle:

angle OSU = angle RSU = (1/2) arc RU = (1/2) x 70 = 35

angle OUS = angle TUS = (1/2) arc TS = (1/2) x 86 = 43

=> As sum of all angles inside triangle UOS is equal to 180

=> UOS = 180 - OSU - OUS = 180 - 35 -43 = 102 deg

Hope this helps!
