Belle, the cat, is looking down at a 78° angle from the top of a tree that is 30 ft tall, when she spots a bird on the ground. How far away is belle from the bird? Round to the nearest hundredth.

[tex]\cos78^\circ=\dfrac{30}x[/tex]

where [tex]x[/tex] is the length of the hypotenuse formed by the tree and Belle's line of sight with the bird. Then the bird is

[tex]x=\dfrac{30}{\cos78^\circ}\approx144.29[/tex]

ft away from Belle.
