Since the triangle is cut in half, I’m guessing it’s 22.5
Answer:
parallel lines
Step-by-step explanation:
the slope is 0
I'm guessing d b are equal and a and c are equal or I don't think we would be able to solve so going on that
if angle d is 57 angle b must also be 57
A parallelegram has angles that add up to 360
So 360= 57+57+2c
Solve
360=114+2c
-114 both sides
246=2c
÷2 both sides
123=c
Answer:
3(y-4) + 3 = 9
3y -12 +3=9
3y -9 = 9
3y = 9+9
3y=18
y=18÷3
∴y=6
