Answer:
78 inches
Step-by-step explanation:
Well if we are assuming that the 60 inches and 50 inches are straight then we can use the Pythagorean theorem to do a^2 + b^2 = c^2, so so a=60 and b=50. so we do that we get 6100, and if we find the square root of that it will be about 78.1024, and that rounded is 78.
