From a hot air balloon, the angle between a radio antenna straight below and the base of the library downtown is 57°, as shown below. If the height of the balloon is 15 miles, what is the distance between the radio antenna and the library?

Best ResponseYou've already chosen the best response.2Alright, so the first step is to figure out which trig function is worth using. To figure this out, I like to find where the angle I know is and then label my sides opposite, adjacent, and hypotenuse.

Best ResponseYou've already chosen the best response.2Cool? The 15 miles side is adjacent to the angle we know. The x side is opposite from that angle. The hypotenuse is always the long side, the one opposite from the right angle.

Best ResponseYou've already chosen the best response.1Well I got the hypotenuse side right :) Okay got the other sides, thanks!

Best ResponseYou've already chosen the best response.2Abbie, the side you know is adjacent. The side you need to know is opposite. See that? Which trig function involves opposite and adjacent?

Best ResponseYou've already chosen the best response.2Yes, it's tangent. Write an equation using tangent. Tan(57) = opposite/adjacent = x/15 solve for x
