Answer:
Step-by-step explanation:
To Find the value of x in this Alternate Interior Angle Relationship..
add [tex]8x+74[/tex] and [tex]2x+56[/tex]
[tex]8x+74+2x+56[/tex] combine like terms
[tex]10x+130=180[/tex]
subtract 130 on both sides
[tex]10x=50[/tex]
divide 10 on both sides
[tex]x=5[/tex]
Now solve for the angle of measure B
∠B=2(5)+56
∠B=10+56
∠B=66°
