Answer:

m<3 = 70 and m<4 = 110

Step-by-step explanation:

<3 and <4 are vertical angles so they add up to 180

(3y + 7) + (5y + 5) = 180

(3y + 5y) + (7 + 5) = 180

8y + 12 = 180

-12 -12

8y = 168

/8 /8

y = 21

find the angle measures:

3(21) + 7

63 + 7

70

5(21) + 5

105 + 5

110

I NEED HELP ASAP PLZZZZ
KonstantinChe [14]

Step-by-step explanation:

We just subsitue 3 for x and -4 for y, so we get

3(3) - 5( - 4) = 9 + 20 = 29

So

a = 29

7(3) + ( - 4) = b

21 - 4 = 17

b = 17

The value of x is ?
allsm [11]
Answer: X = 42

Steps:
(3x + 12) + x = 180
3x + 12 + x = 180
4x + 12 = 180
4x = 180 - 12
4x = 168
x = 168/4
x = 42

Check:
(3x + 12) + x = 180
3x + 12 + x = 180
3(42) + 12 + 42 = 180
126 + 12 + 42 = 180
180 = 180 ✅

I would appreciate the brainliest if this was correct and had helpful & clear steps! :)
