Tangent of 30 degrees is 0.5770.577
30*30
tangent of 30 degrees = 1/2 of the square root of 3 = roughly 0.5773
30 degrees or pi/6
A common tangent is a line which is tangent to two (or more) curves.

mostly it comes from memorization. If sin 30 = 1/2, then arcsin (1/2) = 30

If the pole is on level ground then you have the outline of a right angled triangle with an opposite side of 3 feet and an adjacent angle of 30 degrees. To find the length of the adjacent side (which in effect is the shadow of the pole) use the tangent ratio: tangent = opposite/adjacent which can be rearranged to: adjacent = opposite/tangent adjacent = 3/tangent 30o = 5.196152423 feet Therefore the shadow cast by the pole is 5.2 feet corrected to one decimal place.
The tangent of 0.47 radians is about 0.508. The tangent of 0.47 degrees is about 0.00820.
