Answer:
CD = 3.602019190339
Step-by-step explanation:
CD = DA - CA
DA = DB×Cos(29) = 18.7×cos(29) = 16.355388523507
BA = BA×cos(43) = 18.7×cos(43) = 13.676314220278
CA = BA÷tan(47) = 13.676314220278÷tan(47) = 12.753369333168
Then
CD = 16.355388523507 - 12.753369333168 = 3.602019190339

Answer:
33
Step-by-step explanation:
Let's call their ages m and b.
We have:
m = b + 12
m - 17 = 4(b - 17) → m = 4b - 51
b + 12 = 4b - 51
3b = 63
b = 21
m = 21 + 12 = 33
