Answer: 29 ft
Step-by-step explanation:
Refer to the diagram below
[tex]tan\ 51^o=\dfrac{56}{x}\implies x=\dfrac{56}{tan\ 51^o}\implies x\approx45.35\\\\\\tan\ 37^o=\dfrac{56}{x+y}\implies x+y=\dfrac{56}{tan\ 37^o}\implies y=\dfrac{56}{tan\ 37^o}-x\\\\\\y=\dfrac{56}{tan\ 37^o}-45.35\\\\\\.\ =74.31-45.35\\\\\\.\ \approx 29[/tex]
