Answer:
Explanation:
The mnemonic SOH CAH TOA can remind you of the relevant relationships. The given side is the hypotenuse. x is the side opposite the given angle.
Sin = Opposite/Hypotenuse
sin(51°) = x/(9 ft)
x = (9 ft)sin(51°)
x ≈ 6.99 ft
__
Cos = Adjacent/Hypotenuse
cos(51°) = y/(9 ft)
y = (9 ft)cos(51°)
y ≈ 5.66 ft
