MZWVA = 106°, m_AVU = 4x + 4,
and mZWVU = 21x + 8. Find x.

What is x?

9514 1404 393

  x = 6

Step-by-step explanation:

If we assume that ray VA is between VW and VU, then we have ...

  ∠WVA + ∠AVU = ∠WVU

  106° +(4x +4)° = (21x +8)°

  102 = 17x . . . . . . . . . . . . . subtract 4x+8

  6 = x . . . . . . . . . . divide by 17

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24

time to try the rest on your own! if you put the answers below in a comment, i'll check them for you!
