Answer:

[tex]Angle\ b= 70\°[/tex]

Step-by-step explanation:

The correct question is

Angle a and angle b are vertical angles

Angle a =8x+6

Angle b= 4x+38

Solve for x and find the measure of angle b

we know that

Vertical Angles are the angles opposite each other when two lines cross. They are always congruent.

m∠a=m∠b -----> by vertical angles

substitute the given values

[tex](8x+6)\°=(4x+38)\°[/tex]

solve for x

[tex]8x-4x=38-6[/tex]

[tex]4x=32[/tex]

[tex]x=8[/tex]

Find the measure of angle b

[tex]Angle\ b= (4x+38)\°[/tex]

substitute the value of x

[tex]Angle\ b= (4(8)+38)\°[/tex]

[tex]Angle\ b= 70\°[/tex]

Answer:

70
