Answer:
203 ft.
Explanation:
Since we are given the measurements of two sides, we can use trig to find the angle (or our reference angle, we'll call it x) the sides form.
SOH-CAH-TOA
We'll use cosine since the adjacent and hypotenuse were given for our reference angle.
Cos(x) = (adj/hyp)
Cos(x) = (396/445)
[Cos(x)]cos^-1 = (396/445)(cos^-1)
x ≈ 27.1409 (Nearest ten-thousandth)
And now we find the missing side using our now known angle.
SOH-CAH-TOA
Tan(x) = (opp/adj)
Tan(27.1409) = (opp/396)
0.5126 ≈ (opp/396)
(0.5126)(396) ≈ (opp/396)(396)
Opp = 203
Missing Side = 203 ft
