A painting in an art gallery has height h and is hung so that its lower edge is a distance d above the eye of an abserver. How far from the wall should the observer stand to get the best view?(maximize the angle) - the answer is 5-2root5 from A I dont know the reason

step-by-step explanation: h: (- 3, 6)

m: (1, - 2)

o: (7, 6)

r: (- 9, - 2)

midpoint of hm: (- 1, 2)

midpoint of or: (- 1, 2)

therefore, b is the midpoint of both diagonals bisect each other !

to prove the diagonals are perpendicular, show that the product of the slopes = - 1

a. the are of the rectangle is 18.25

b. 18.25 times two is 36.50

rae me : d
