Question 120543: length of 3rd side of triangle. ab=9.5 bc=7 ac=???
i am trying to lay out the stringers for a stairway and need to know the length of the one side. the triangles are the stair steps.

my assumption is that you need the longest side?

by Pythagoras, the sum of the squares of the short sides equals the square of the long side

x^2=9.5^2+7^2 __ x^2=90.25+49 __ x^2=139.25 __ x=11.80

good luck with the stairs
