Are you being asked to solve for A? B? [tex]A^{2} + B ^{2} = C^{2} [/tex] [tex]A ^{2} +B ^{2} =(2.9) ^{2} [/tex] [tex]A ^{2} + B^{2} =8.41[/tex]
Solve for A: [tex]A^2=8.41-B^2[/tex] Take a plus of minus square root A=[tex] \sqrt{-b^2+8.41} [/tex] A=[tex]- \sqrt{-b^2+8.41} [/tex]
Solve B: [tex]A^2+B^2=8.41[/tex] [tex]B^2=-A^2+8.41[/tex] Take plus or minus square roots [tex]B= \sqrt{A^2+8.41} [/tex] [tex]B= -\sqrt{A^2+8.41} [/tex]
