Answer:

<em />

Step-by-step explanation:

7 + 4y = 39

Rearrange:

4y + 7 = 39

Subtract 7 from both sides:

4y + 7 = 39

- 7 -7

4y = 32

Divide both sides by 4:

4/4 = y

32/4 = 8

HELP upvote brainliest Write the statement that would go in the empty box to complete the flow proof below.

Degger [83]

Here, ∠WVX = ∠WZY
& ∠W = ∠W [ Reflexive Property ]

Triangles have the constant sum, so they would be: equal.
WVX + WXV + W = W + WZY + WYZ
WXY = WYZ [ ∠WVX = ∠WZY ]

Now, As all the angles are equal, we conclude:
ΔXVW ≈ ΔYZW [ By ASA Postulate ]

Hope this helps!
