Answer:
yes 
Explanation:
screens are measured from corner to corner meaning that from the top left to bottom right the tv is 72 inches 
since we know the tv is 36 in tall and 72 across we can use the Pythagorean theorem to find how wide it is by doing 72^2-36^2
so the tv is 62.35 in wide 
so it will fit in the 70-inch wide gap
