Jia is tiling a floor. The floor is a square with side
NNADVOKAT [17]

Answer:

36 tiles

Step-by-step explanation:

First, find area of the square floor knowing the formula as;

Area= s^{2}

where s= side of a square.

If one side of the floor is 12 feet, then Area= 12^{2} = 144ft^{2}

Next, find the area of each tile using the same formula and given s=2 feet;

Area(tile) = 2^{2} = 4ft^{2}

To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles

What is the measure of each angle? Show your work!
nalin [4]

Answer:

pos: 99.  Sor: 17.    roq: 64

Step-by-step explanation:

(5x+4)+(x-2)+(3x+7)=180

we add the angles to 180 because straight lines are equal to 180

5x+4+x-2+3x+7=180

5x+x+3x+4-2+7=180

9x+9=180

9x=

9x=171

x=19

then we plug x in

5(19)+4 +  (19)-2  +3(19)+7 = 180

angles (left right)

99.   17.     64.
