Answer:

9. C

10. A

Step-by-step explanation:

9. a/sinA = c/sinC

69/sin49 = 88/sinC

sinC = 0.9625281603

C = 74.26540014°

10. 30/Sin53 = 37/sinC

sinC = 0.9849837957

C = 80.05825382

B = 180 - 53 - 80.05825382

B = 46.94174618°

Answer:

55 ft.

Step-by-step explanation:

First find the area of Lot X

67 • 70 = 4,690

Subtract the are of Lot X from the total area

8,375 - 4,690 = 3,685

3,685 is the area of Lot Y

Now divide 3,685 by the length of Lot Y : 67

3,685 ÷ 67 = 55

The width of Lot Y is 55 ft.

Hope this helps!

A square is cut from a rectangle. The side length of the square is half of the unknown width w. The area of the shaded region is
Virty [35]

Answer:

  • See below

Step-by-step explanation:

<u>The side of the square is w/2, then its area is:</u>

  • A = (w/2)² = w²/4

<u>The shaded area is the difference of areas of the rectangle and the square:</u>

  • 14w - w²/4 = 84

<u>This can be simplified:</u>

  • 56w - w² = 336
  • w² - 56w + 336 = 0

Why does -2^6 equal -64 but -2 x -2 x -2 x -2 x -2 x -2 equal 64?<br> (The x's are multiplication)
NikAS [45]

Answer:

when there are no parentheses around the base, this being -2 we put parentheses around the the 2 and the exponent so it will look like -(2^6) making whatever answer you get negative.

when you put parentheses around the base (-2)^6 you will get 64
