Question

What is the exterior angle?

Answer 1

Answer:

angle YUT = 120

Step-by-step explanation:

in Triangle SUT

angle 70 + angle 50 + angle x = 180

 70 + 50 + x = 180

 120 + x = 180

 x = 180 - 120

 x = 60

angle SUT = 60

angle SUT + angle YUT = 180 ( straight line)

60 + x = 180

 x = 120

Therefore angle YUT ( exterior angle ) = 120
