A 20-Meter Line Is Used to Tether a Helium-Filled Balloon $$\sin 85 ^ { \circ } = \frac { h } { 20 }$$

Multiple Choice

A 20-meter line is used to tether a helium-filled balloon.Because of a breeze,the line makes an angle of approximately 85° with the ground.Use a trigonometric function to write an equation involving the unknown quantity. ?

A) $$\sin 85 ^ { \circ } = \frac { h } { 20 }$$ (where h is height. )
B) $\cos 85 ^ { \circ } = \frac { h } { 20 }$ (where h is height. )
C) $\cos 85 ^ { \circ } = \frac { 20 } { h }$ (where h is height. )
D) $\sin 85 ^ { \circ } = \frac { 20 } { h }$ (where h is height. )
E) $\tan 85 ^ { \circ } = \frac { h } { 20 }$ (where h is height. )
