Equation: y=x-2 , Hope this helps!
Answer:
You cant find that out. X and Y are like two different animals in a zoo, and XY is a whole other animal, you cant combine two animals in the same cage, so X and Y cant turn into XY. You could do:
X = 5
Y = 2
X + Y = ?
In this case the answer would be seven.
-8x-12+y^2
This is my aswer haha
4x+5=8x-11 solve for X then plug back into 4x+5 for the measure of angle QST
