Lines b and c are parallel. what is the measure of < 6? m< 6 = 45 m< 6 = 54 m< 6 = 117 m< 6 = 126

m<6 = 54

St,ep-by-step explanation:

Lines b and c are parallel.

13x +9 and 5x+9 are consecutive exterior angles.

Consecutive exterior angles are supplementary.

Now we solve for x. combine like terms

Subtract 18 from both sides

Divide both sides by 18

x=9

So the value of x=9

angle 6 and 5x+9 are vertical opposite angles . they are equal

m<6= 5x+9

Plug in 9 for x

m<6= 5(9)+9=54

m<6 = 54

first one because it can't have a fraction in it
