Question

The three interior angle measures of this triangle

Answer 1

Z=80
X=30
Y=70
These are the follow answers it's just supplementary angles on a straight line

Answer 2

Remember that every line segment equals 180 degrees. So for X it would be 30 because 150+30+180 and so then Z would equal 80. Now for Y its different but remember that a triangle has a 180 degree so if x=30 and z=80 then y=70 because 30+80=110 and 110+70=180. Got it?
