I did try that, but no sucess now the game says 73 of 80 foot thrown tomahawk enemy kill, this is weird, or am i doing something wrong?

I am stuck at this challenge for long time now, SHARPSHOOTER 4 80 FEET TOMHAWK KILL, I tried everything but still nothing it now says 70 feet of 80 feet left, I don't know how to measure 10 feet distance now, please help anyone who is facing similar situation, I have completed everything just this Sharpshooter challenge is left, I am physically disabled, suffering from a brain disorder, any help will be appreciated, thanks in advance folks,
