1.) (sec x)(cot x) = (hypotenuse/adjacent)(adjacent/opposite) =

(hypotenuse/opposite)

2.) cot 50 = x/6
x = 6 cot 50
3.) tan y
4.) cos x = (12/13)x = 22.62 degrees
5.) sin y = 5/14y = 20.92
6.) sin 30 = (1/h)h = 2 meters
7.) cos 0° = 1, because the cosine and sine are complements
8.) sin y = (a/6) ; tan y = (a/b)
cos y = (b/6)
9.) tan 50 = (ac/3)
ac = 3 tan 50
10.) sin 40 = (h/220)h = 220 sin 40
