Answer:
88 in
Step-by-step explanation:
You will need to use the Pythagorean theorem for this question which is a^2+b^2=c^. The diagonal will always be c, therefore you need to plug 80 in for a and 36 in for b. Add those together, and you should be left with 7696=c^2. Take the square root of both, and you will get your answer :)
