Question

Answer this please thanks

Answer 1

z=5, m<b=66 degrees

Explanation:

8z+74+2z+56=180

10z+130=180

10z=50

z=5

Answer 2

Explanation:

To Find the value of x in this Alternate Interior Angle Relationship..

add
`8x+74` and
`2x+56`

`8x+74+2x+56` combine like terms

`10x+130=180`

subtract 130 on both sides

`10x=50`

divide 10 on both sides

`x=5`

Now solve for the angle of measure B

∠B=2(5)+56

∠B=10+56

∠B=66°
