If A = 60o and B = 30o, verify that
Use this equation:(sinx)^2+(cos)^2=1(sinx)^2=1-(cosx)^2sinx=sqrt(1-(cosx)^2)tanA = sqrt(1-(cosA)^2)/cosA = sinA/cosA = tanA
SImple....using trig rules to solve.A= -0.05+0.1n, 0+0.2n(I'd show work..but I'm in my trig class right now..and my laptop has to be off. :( )Thus, your answer.
