Optics Question

Answer 1

A system of two lenses forms an image of an arrow at x = x3 = 69.2 cm. The first lens is a diverging lens located at x = 0 and has a focal length of magnitude f1 = 10.4 cm. The second lens is located at x = x2 = 29.8 cm and has an unknown focal length. The tip of the object arrow is located at (x,y) = (xo, yo) = (-42.3 cm, 13.9 cm).

Answer 2

What is f2, the focal length of the second lens. If the lens is a converging lens, f2 is positive. If the lens is a diverging lens, f2 is negative.

Answer 3

I solved for x1, -8.35, I solved for y1 2.74, but I cant figure this out. Thanks
