Question

find the values of the following tan 75°​

Answer 1

Step-by-step explanation:

Let us write 75 degrees as a sum of two angles 45 degrees and 30 degrees.

We have written 75 degrees as a sum of two angles so that we can use the trigonometric formula.

tan (x+y) = (tanx + tany) / (1 - tan x tan y)

On substituting the value of x as 45 degree and y as 30 degree, we get,

tan (45°+30°) = (tan45°+ tan30°) / (1-tan45° tan30°)

= {1+ (1/√3)} / {1-(1/√3)}
