X could be any of those values.

**Answer:**

**Step-by-step explanation:**

area of sector=πr²/4=π ×6²/4=9 π ft²

area of one triangle= 1/2×6×6=18 ft²

area of three triangles=3×18=54 ft²

area of sector +area of three triangles=54+9 π ft²

area of circle=π×6²=36 π ft²

area of shaded region=36 π-9π-54=27 π-54=27(π-2) ft²

The hypotenuse is sqrt(45) or 6.708

The angle is 63.43 degrees

Answer:

6.99x 10^(7) = 69,900,000

3.61x10^(7) = 36,100,000

8.3x10^(6) = 8,300,000

question 1

114,300,00 is them all added up

1.143x10^(9) is standard form

and i do belive part a's answer is the 6.99x10^(7) and so on and so forth. I hope this helps. X3 i did my best.
