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

How do you add 1/10 plus 8/100

zysi [14]

To add 1/10 and 8/100, they must have the same denominator.

To do this, multiply 1/10 by 10/10 (which equals one, so it doesn't change the value of the fraction).

Now you have 10/100 and 8/100. To add them, simply add the numerators and keep the denominators the same.

This results in 18/100, which can be simplified to 9/50.
