WebAs suggested by Jonas: 1) Draw a right triangle and label one of the (non 90 ∘) angles α. 2) You know that the tangent of α is 1 2. Since tan = opposite adjacent, you can label the side of the triangle adjacent to α "1" and the opposite side "2". 3) By the Pythagorean theorem, you can find the length of the hypotenuse of the triangle. Webcosine: [noun] a trigonometric function that for an acute angle is the ratio between the leg adjacent to the angle when it is considered part of a right triangle and the hypotenuse.
