The tangent of an angle is equal to the ratio of sine and cosine functions of the same angle, in the right angle triangle. Therefore, once we have found the values of sin 15 degrees and cos 15 degrees, we can easily find the corresponding tangent value. Step 1: Plug the angle value, in degrees, in the formula above: radian measure = (75 × π)/180. Step 2: Rearrange the terms: radian measure = π × 75/180. Step 3: Reduce or simplify the fraction of π if necessary. Calculating the gcd of 75 and 180 [gcd(75,180)], we've found that it equals 15. Precalculus.
