Answer:

BC = 25

Step-by-step explanation:

If the base angles are equal, then the sides opposite them are as well.

4x + 4 = 6x - 14 Subtract 4x from both sides
4x - 4x + 4 = 6x - 4x - 14 Combine
4 = 2x - 14 Add 14 to both sides
4 + 14 = 2x - 14 + 14 Combine
18 = 2x Divide by 2 and switch
2x/2 = 18/2 Combine
x = 9

But that's not what you are asked for. You want the value of 2x + 7

BC = 2x + 7
BC = 2*9 + 7
BC = 25

m - 3 = 3(b - 3)
m - 3 = 3b - 9
m + 6 = 3b
m/3 + 2 = b

5 years from now:
m + 5 = 2(b + 5)
m + 5 = 2b + 10
m - 5 = 2b
m/2 - 5/2 = b

combine:
m/3 + 2 = m/2 - 5/2

1. multiply by 6
2m + 12 = 3m - 15

2. add 15 - 2m to both sides
27 = m

Marry is 27 years old.

Use the Sine Law: $\frac{sin(A)}{a} = \frac{sin(B)}{b} = \frac{sin(C)}{c}$

In this case:
$\frac{sin(44)}{17}=\frac{sin(60)}{e}$
therefore:
$e=17\frac{sin(60)}{sin(44)} \approx 21.2$
