Question

What is the exterior angle?

Answer 1

angle YUT = 120

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
