Answer:
7. Interior of a any triangle add up to 180. Therefore x+40+y=180
We only need to find the value of x or y in order to get the value for the other.
angle y and the 117° angle are suplementary. Supplementary angles add up to 180. THerefore y=180-117
y=63°
therefore 63+40+x=180
103+x=180
x=77
y=63
8. By following the same rules as the one above im going to have you solve it just so that you get some practice. Sorry if that makes u mad :/
Some things to note while u do number 8 is that 110 and the angle opposite to it which isn't labeled are supplementary. With that knowledge you can figure out the measure of that angle and then use the rule that all interior angles of a triangle equal 180 to find what x must equal.
I advise you to try and figure it out but If you still cant find the answer then just look below
