We see two parallel lines crossed by a transversal.
The two labelled angles are alternate interior angles, hence they are equal.
The equality allows us to equate the two expressions and hence solve for x.
8x-3=5x+42
transpose terms
8x-5x=42+3
solve for x
3x=45
so x=45/3=15.
This means 5x+42=5*15+42=75+42=117 degrees.
<span>Multiply the length and width together to get the total required area - 5*8 = 40. Now each tile covers 3 inches and you need to cover 40 feet, so convert feet into inches by multiplying 40 by 12 (480). Now divide 480 (desired area) by 3 (how much each tile covers) to get 160 - the amount of tiles you'll need.
Sorry, didn't realize I didn't post it as an answer. But no problem!</span>
Answer:
i want to say 36, im not 100% sure though
