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]
