Use this equation:
(sinx)^2+(cos)^2=1
(sinx)^2=1-(cosx)^2
sinx=sqrt(1-(cosx)^2)

tanA = sqrt(1-(cosA)^2)/cosA = sinA/cosA = tanA

SImple....

using trig rules to solve.

A= -0.05+0.1*n, 0+0.2*n

(I'd show work..but I'm in my trig class right now..and my laptop has to be off. :( )

Thus, your answer.
