Answer:

x = 20 degrees

Step-by-step explanation:

We know this because angles next to each other in parallelograms add up to 180 degrees, so if we create an equation, 3x + 120 = 180 meaning that 3x = 60, which means that x = 20 degrees.

What is the exterior angle?

olganol [36]

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
