Tan(60) = Sin(60)/ Cos(60) Sin(60) = sqrt(3)/2 Cos(60) = 1/2 Hence Sin(60) / Cos(60) = [sqrt(3) / 2] / [1/2} => sqrt(3) / 2 X 2/1 sqrt(3) Hence Tan(60) = sqrt(3) = Numerically = 1.732050808....

Co-60 is an isotope of Co-59, which is a common component of steel. You get Co-60 by irradiating it with neutrons, so you get Co-60 in nuclear reactors, or anywhere else you have a neutron flux.

Atomic Mass or mass no
The "60" in Co-60 represents the atomic mass number of the cobalt isotope. It indicates that the cobalt nucleus contains 60 protons and neutrons combined.
In the beta minus decay of cobalt-60 (Co-60), a neutron in the nucleus is transformed into a proton, resulting in the emission of a beta particle (electron) and an antineutrino. The balanced nuclear reaction can be represented as: [ ^{60}{27}\text{Co} \rightarrow ^{60}{28}\text{Ni} + e^- + \bar{\nu} ] Here, Co-60 decays into nickel-60 (Ni-60), with the emission of a beta particle (e^-) and an antineutrino (ν̄).
Cobalt is a metal element. Atomic mass of it is 58.
Providing that the pole is on level ground you have the outline of a right angled triangle with an adjacent side of 92 ft (the shadow of the pole) and a opposite side of 60 ft (the height of the pole). To find the angle of elevation use the tangent ratio. Tangent = Opposite/Adjacent Tangent = 60/92 = 0.652173913 Tan-1(0.652173913) = 33.11134196 degrees Therefore the angle of elevation is 33o correct to two significant figures.
A cobalt atom with have 27 electrons regardless of the isotope.
