Answer:
Step-by-step explanation:
Angle C and angle with 120 degrees measure are alternate and their measurement is equal so C = 120
angle C and angle B are supplementary and so their sum is equal to 180
B = 180 - 120
B = 60
angle D and angle B are also alternate so their measure is also equal to each other therefore
D = 60
Answer: x= -7, y= 0
Hope this helped , if it did mark me brainliest pls!
Sub x=-5+2y
2(-5+2y)+4y=14
y=3
Your Answer Is...
12.
