Answer:
Hi there!
The correct answer is: 891.77 ft.
Step-by-step explanation:
if you look at the picture you provided it says a bunch formulas such as sine, cosine, and tangent. What they all mean is sine = opposite over hypotenuse
cosine = adjacent over hypotenuse and tangent = opposite over adjacent
for this question is especially we can see that the missing side length is directly opposite of the angle given additionally you're also given the hypotenuse (longest side of a triangle). then if you look back at all the equations you are given sine is the only one that deals with the hypotenuse and the opposite side. then all you got to do is plug the values into the equation.
sin(48) = x/1200 multiply 1200 on both sides and you get x=891.77
