# Math Help - Trigo qn

1. ## Trigo qn

Given that tan(q+60°) = 2 , find the rationalized value of cot q.

For this qn, i just dunno how to convert the decimal form to surds form and
the paper's answer is cot q = 8+5 sqr 3 (in surds form)
my answer in decimal form is 16.66025404

2. Tan 60 degrees = sqr of 3

Does this help?

3. Thanks!! It helps!!!~
