Will give brainliest!!! 7. CONSTRUCTION A door frame is
80 inches tall and 36 inches wide. What
is the length of a diagonal of the door
frame? Round to the nearest tenth of an
inch.

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

Step-by-step explanation:

7696=c^2
