Angle 6= (11x+8) and angle 7=(12x-4) what is the measure of angle 4
Hitman42 [59]

Answer:

Answer is m∠4=40

Step-by-step explanation:

take note that m∠6 & m∠7 are vertical angles. Vertical angles are equal to each other, therefore m∠6 is equal to m∠7.

m∠6 = m∠7 (vertical angles)

11x + 8 = 12x – 4

12x - 11x = 8 + 4

x = 12

so

m∠6 = 11x + 8  

m∠6 = 11(12) + 8

m∠6 = 132 + 8

m∠6 = 140

m∠4 = 180 - m<6

m∠4 = 180 - 140

m∠4 = 40

Which two lines are parallel?
GaryK [48]

Answer:

First turn 3x + y = -5 to slope-intercept form (y=mx+b) by subtracting 3x in order to move it to the other side, to get

y = -3x - 5.

So now you have all three lines in proper slope-intercept form. (Don't worry about

y = 7 - 3x, it's still in slope-intercept form, despite the y-intercept and slope being swapped.)

<u>Here are the lines rewritten below</u>.⤵⤵⤵

1. y = -3x - 5

2. y = -3x + 7 or y = 7 - 3x (either way works)

3. y = -3x + 2.5

As we can see, all three lines are parallel.

Because all the slopes are the same and the y-intercepts are different. If the slopes were different, the lines wouldn't be parallel.

I also graphed the lines above, so you can see what I mean.⤴⤴⤴ Hope this helped :)
