Finding Exact Value using Trig Identities and Complementary Angle Theorem

[Dundee3]

Hey guys, I've been trying to wrap my mind around this problem but I've really come up short.

Any help would be amazing.

If tanX=10 Find the exact value of cot(pi/2 - x)

Among the identities You find in...

List of trigonometric identities - Wikipedia, the free encyclopedia

... there is $\displaystyle \cot (\frac{\pi}{2} - x) = \tan x$...

Kind regards
