Step-by-step explanation:

Corresponding angles of congruent triangles are congruent.

  angle B = angle E

  3v +4 = 8v -6

  10 = 5v

  v = 2

Then the measure of angle B is

  3v +4 = 3(2) +4 = 10 . . . measure of ∠B

10

I hope this helps and good luck

Step-by-step explanation:

Using the identity (x + 0.5)^2 = x(x + 1) + 0.25:

4.5^2 = 4 * 5 + 0.25 = 20.25

Also 4.45^2 = 19.8

so  4.47^2 will be closer to 20 than 4.5^2.
