Answer:
y = 45°
Step-by-step explanation:
4 sides = 360°
(2y+1)° + y° + 112° + 112° = 360°
2y + y = 360 - 112 - 112 - 1
3y = 135
y = 135÷3
= 45°
Step by step subtract 20 from both sides and then subtract 20 from 9 to get -11
Answer: C=-11
True! Because T is the defining letter of the line, so it would be true!
