Use pythagoras theorem |dw:1448189848298:dw| To find A \[A=\sqrt{C^2-B^2}\] To find B \[B=\sqrt{C^2-A^2}\] To find C \[C=\sqrt{A^2+B^2}\]

OpenStudy (anonymous):

|dw:1448190041744:dw|\[w=\sqrt{7^2-3^2}\]\[w=\sqrt{49-9}\]\[w=\sqrt{40}\]\[w=?\] solve it @Diana.xL

OpenStudy (anonymous):

Then compare this value of w with the given options

OpenStudy (anonymous):

If the value of w is the same as the given option that is the answer

OpenStudy (diana.xl):

it would be \[2\sqrt{10}\]

OpenStudy (anonymous):

correct!
