Sin is equal to opposite over hypotenuse With this we know that Opposite = sqrt(12) Hypotenuse = 4 To find adjacent we need to use the Pythagorean theorem 12 + adj^2 = 4^2 We then solve for adj 12 + adj^2 =16 adj^2 =4 adj =2 Now that we have opposite, adjacent, and hypotenuse, we can find cos and tan Cos is equal to adj/hypotenuse Cos = 2/4 = 1/2 Tan is equal to opp/adj Tan = sqrt(12)/2
