How do we find the formula for hypotenuse of the triangle?
(hhx/r)
(Just for x)

Best ResponseYou've already chosen the best response.1we have two points : ( 0,h) and (r,0)

Best ResponseYou've already chosen the best response.1hence the slope : (h0) /(0r) = h/r and using y = y1 + m(xx1) we get : y = h hx/r

Best ResponseYou've already chosen the best response.0i can see how we get the slope

Best ResponseYou've already chosen the best response.1we can take one of the points : (0,h) or (r,0) to be (x1,y1) in both cases we will get the same answer

Best ResponseYou've already chosen the best response.1lets take the (r,0) so y1 = 0 : y = 0 + h/r(xr) y = h hx/r

Best ResponseYou've already chosen the best response.1we find slope then we can choose any given point on the line to construct our line equation :)
