Lines b and c are parallel. what is the measure of angle 6? m6 = 45° m6 = 54° m6 = 117° m6 = 126°

54 degrees

Step-by-step explanation:

If these two lines are parallel, than angles 1 and 7 are supplementary.

13x+9+5x+9=180

18x+18=180

x+1=10

x=9

Angle 6 and 7 are vertical angles, so they are equal. Therefore, angle 6 is:

5x+9=5(9)+9=54

Hope this helps!!

Step-by-step explanation:

i dont know bc i cant see the problem

Step-by-step explanation:

There are no pictures but if the question is this the pic is given above , So the answer will be this :

Answer :

m2 = 50

7x+1+18x+4=180

7x+1+18x+4=18025x+5=180

7x+1+18x+4=18025x+5=18025x=175

7x+1+18x+4=18025x+5=18025x=175x=7

7x+1+18x+4=18025x+5=18025x=175x=7m2= 7(7)+1 = 50

Step-by-step explanation:

Hope it works out !!

We don't see the angles or lines

Step-by-step explanation:

∠6 = 54°

Step-by-step explanation:

Since b and c are parallel lines, then

∠8 = 13x + 9 ( alternate exterior angle ) and

∠6 = 5x + 9 ( vertical angles )

∠6 and ∠8 form a straight angle and are supplementary, thus

13x + 9 + 5x + 9 = 180, that is

18x + 18 = 180 ( subtract 18 from both sides )

18x = 162 ( divide both sides by 18 )

x = 9

Hence

∠6 = 5x + 9 = (5 × 9) + 9 = 45 + 9 = 54°
