Answer:
Step-by-step explanation:
We are asked to justify the given steps:
a) AB+BC=AC : Segment addition postulate
b) 2x+6x+8 = 32: Substitution (substituted 2x for AB and 6x+8 for BC and 32 for AC)
c) 8x+8 =32 :Simplification
d)8x=24: Addition property of equality
e) x=3: Multiplication property of equality .....
Y-9 + y/2 = 180
Add nine to each side
y+y/2=189
Multiply each side by two
2y+y=378
Add the y's together
3y=378
Divide it all by three
y=126
so, Angle B is 126 degrees
I hope that helps!
