Answer:
70
Step-by-step explanation:
You know the inside of a tringle has a total of 180 degrees. You also know that the angle V sits on a plane that is also 180.
Start by getting the value of angle V, so 180-120 = 60
With that, you can find angle U. Set up your formula as
U = 180 - 50 (Angle T) - 60 (Angle v)
U = 180 - 50 - 60 = 70
You can apply the same knowledge to the other questions as well.
