if m^2 + m'^2 + 2mm'cosA = 1 , n^2 + n'^2 + 2nn'cosA = 1 , and , mn + m'n' + (mn' + m'n)cosA = 0 THEN WHAT IS m^2 + n^2 ???? please explain and show the steps

if m^2 + m'^2 + 2mm'cosA = 1  ,


n^2 + n'^2 + 2nn'cosA = 1  ,


and ,   mn + m'n' + (mn' + m'n)cosA = 0


THEN WHAT IS m^2 + n^2 ????


please explain and show the steps
