Question

xtan27 = tan11sqrt(1600-x^2)
can someone show steps to reaarage this to x^2+=?

Answer 1

fan and medal

Answer 2

xtan27 = tan11sqrt(1600-x^2)
x^2tan^2(27) = (1600-x^2)tan^2(11)
x^2tan^2(27) = 1600tan^2(11) - x^2tan^2(11)
x^2[tan^2(27) + tan^2(11)] = 1600tan^2(11)

so x^2 = 1600tan^2(11)/[tan^2(27) + tan^2(11)?

Answer 3

you need to work some of this out yourself. not get everyone else to do it
