joey is putting up an antenna. at the 30 foot mark, he attaches a 50 foot guy wire. what angle does the guy wire form with the antenna.
We know the adjacent side (30) and the hypoteneuse (50).....and the trig function that relates these two is the cosine....so we have
cosΘ = 30 / 50
So, using the inverse sine to find Θ, we have
cos-1 (30/50) = Θ = about 53.13°
