Best ResponseYou've already chosen the best response.0K so a midpoint is basically an average of the x points and of the y points. The formula is x1+x2 divided by 2, y1+y2 divided by 2. If we do this we get (2+3) (1+2)  &  2 2 5/2, 3/2= (2.5,1.5)

Best ResponseYou've already chosen the best response.0This can be solved with trigonometry. The hypotenuse has been given and the opposite side is needed. In this case, we will need to use sine. sin = opposite/hypotenuse let the opposite side length be y so sin(36) = y/220 220sin(36) = y plug that into a scientific calculator and you get 129.3ft so the answer is D
