Answer:
A. x = 68, y = 75
Step-by-step explanation:
So you see how those three angles all make a straight line? that's called complementary, where it all makes 180Ëš.
So, you know that...
(x-1)Ëš + 40Ëš + (y-2)Ëš = 180Ëš
I'm not sure what that 74Ëš is about, but what I would do is plug in the options until you get 180 degrees.
In this case, its the first option, A.
(68-1)Ëš + 40Ëš + (75-20)Ëš = 180Ëš, which is true! so its A.
