Using the figure and the Pythagorean theorem, we can write two equations which both equal e2 : e2=b2-(w-x)2 and e2=a2-x2 Set them equal to each other and solve for b2 . Triangle LKM with a red line drawn parallel to KM labeled Question 17 options: b squared equals a squared minus w squared plus 2 w x b squared equals a squared minus w squared minus 2 w x b squared equals a squared plus w squared plus 2 w x b squared equals a squared plus w squared minus 2 w x
