Answer:

  • x = 6.99 ft
  • y = 5.66 ft

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
