    \[T= \frac{ Mg }{ 2 \sin 45 }\]

    The answer says it = Mg/2 what happens to the root2 / 2

    hahha Just wanna know how they got from \[2T *\frac{ \sqrt{2} }{ 2 } = Mg \] to\[T = \]

    Yeah , but I don't see how they're getting rid of the square root?

    so, I guess you're asking:\[\sqrt{2}T =Mg\] \[T = \frac{Mg }{ \sqrt{2}}\] \[T = \frac{Mg }{ \sqrt{2}} \frac{ \sqrt{2} }{ \sqrt{2} }\]

    But they got T = Mg/2 in the book that I'm using?

    maybe the answer is actually Mg/2 ... I don't know.

    yep, you're right... should be sqrt(2) Mg /2
