Sin= Opposite/Hypotenuse Cos= Adjacent/Hypotenuse Tan= Opposite/Adjacent
What is the hypotenuse of the right triangle if the angle measures are 90 degrees 70 degrees and 20 degrees and one leg length is 850?
It depends on which leg is 850... If the leg on the bottom is 850, then you do 850/cos(20) (which gives you 904.55), if it is the leg on the side, then you do 850/sin(20) (which gives you 2485.233). You get this by solving for the formula Cos(Angle)=Adjacent/Hypotenuse, or Sin(Angle) = Opposite/Hypotenuse.
What is the hypotenuse of a right triangle with the adjacent side measuring 4.0 and a degree of 58?
Cos(58) = 4/Hypotenuse so H = 4/Cos(58) = 7.55 units.
What is the trigonometric ratio for Cos?
the adjacent side over the hypotenuse
