Question 656717
 I am building an A frame. The height will be 144 inches from ground to peak. The base will be 144 inches long. How do I figure how long my other 2 sides will be?
An A frame is made up of two right triangles, the hypotenuse of the triangle is
 the length of the other two sides,
 the legs of the triangle: half the base (72) and the height (144)
:
h = {{{sqrt(72^2+144^2)}}}
h ~ 161 inches, the length of the other two sides
