WebTo find the tangent value of 15 degrees, we are going to use one of these trigonometric formulae. Also, we will find out the value of tan 15, with the help of the other two ratios, which is sine and cosine, and also with the help of trigonometry table. Tan (15 °) can be found if we know the value of sin 15 degrees and cos 15 degrees. The ... WebNov 8, 2016 · Explanation: tan(75) = tan(30 +45) now tan(A+ B) = tanA +tanB 1 − tanAtanB. tan(75) = tan(30 +45) = tan30 +tan45 1 − tan30tan45. tan30 = √3 3,tan45 = 1. ∴ tan75 = √3 3 +1 1 − √3 3. = √3 + 3 3 − √3 × 3 +√3 3 +√3. = 3√3 + 3 + 9 + 3√3 6. = 12+ 6√3 6.
