What is the tan 60 degrees?

The tangent of 60 degrees is equal to the square root of 3, or approximately 1.732. This value can be derived from the properties of a 30-60-90 triangle, where the ratio of the lengths of the sides opposite the angles gives the tangent. Specifically, in a 30-60-90 triangle, the side opposite the 60-degree angle is √3 times the length of the side opposite the 30-degree angle.
