As others have said, that is not a good angle for a shot. But to address the arrow situation, the best solution I have found for an arrow that will maintain its structural integrity during most impacts is an Arrow Dynamics Hammerhead or Hammerhead Lite with a 100 grain brass insert and an aluminum collar that have been glued in with marine grade, slow-set, high-strength epoxy. I have never had any impact from any angle of shot cause one of those arrows to break. The fact that the arrow does not break does not mean that you will get sufficient penetration to kill the animal if you strike heavy bone or other barriers to penetration, but at least you are maximizing your chances of a kill when you take a good shot and just hit something you didn't expect.
