Question 569279: learning sin, cos and tan, and we are having trouble getting the correct answer for: a right triangle has a hypotenuse of 17 and an angle of 54 degrees, and we are asked to find side "w". The answer is 13.8, but we aren't getting it. We know the formula is tan=opposite/adjacent, so we put in calculator Tan 54x17 (tan54=w/17)....please help!

hypotenuse = 17
for tan you need to know the opposite & adjacent sidex
Cos 54 = adjacent side / hypotenuse
cos 54 * hypotenuse = adjacent side
adjacent side = 9.99
opposite side/adjacent side = Tan
9.99 * tan(54 degrees) = 13.7500554
