please help

An observer (O) spots a plane flying at a 35° angle to his horizontal line of sight. If the plane is flying at an altitude of 17,000 ft., what is the distance (x) from the plane (P) to the observer (O)?

A right triangle is shown with one angle marked 35 degrees, one side marked x and the height marked 17000 feet.

20,757 feet

24,251 feet

29,639 feet

31,262 feet

What two sides of the triangle are you given?

anonymous · Answer

*in terms of the 35 degree angle?

anonymous · Answer

The 3 sides are: opposite, adjacent and hypotenuse

anonymous · Answer

wait so there's no answer ? @larryboxaplenty

anonymous · Answer

You left soI figured that you went elsewhere

anonymous · Answer

They give you the hypotenuse and opposite side in terms of the 35 degrees.  What trig function uses the those two sides?

anonymous · Answer

sin, cos, or tan?

anonymous · Answer

no my computer was acting up sorry

anonymous · Answer

Do you know?

anonymous · Answer

idk but this is the picture

anonymous · Answer

It's Sin.  Sinx = Opposite/Hypotenuse.
Therefore: Sin(35 degrees) = 17000/x

anonymous · Answer

Can you solve for x from here?

anonymous · Answer

is it C ? im really not good at this
