Question

A kite is flying 70 feet above the ground and is attached to a string tied to a stake on the ground. The angle of elevation formed by the string and the ground is 40°. Find the length of the string to the nearest foot.

Answer 1

recall your SOH CAH TOA \(\bf sin(\theta)=\cfrac{opposite}{hypotenuse}
\qquad \qquad
% cosine
cos(\theta)=\cfrac{adjacent}{hypotenuse}

\\ \quad \\
% tangent
tan(\theta)=\cfrac{opposite}{adjacent}\)

Answer 2

so, you have the angle
you have the opposite side
and you need the hypotenuse

so which ratio is it then? :)

Answer 3

Ahh I dont know :(
Math is not my strong suit. Thank you for the help though, I will keep on trying. :)

Answer 4

ok... lemme put it differently
off all three ratios there, or identities
which one ONLY includes
the angle
the opposite side
and the hypotenuse?

Answer 5

Oh wow!! How could I not have seen it before?! Thank you so much for the help. :)
