Answer:

y = 90°

Step-by-step explanation:

You do 110° + 80° which is 180 divides by two because there is a straight line in the middle of it. I don't know how to explain it.

Answer:

90 degrees

Step-by-step explanation:

you have angles of 110 and 70 on the sides. The triangle altogether equals 180 but that doesn't matter in this equation. Since y is directly between the two angles that are given, it is 90.

110-70=40/2=20 so add 20 to 70 and subtract 20 from 110 so you get 90.
