A. 0

Step-by-step explanation:

23/40 is approximately 1/2.

The relative locations of a swing set, a garden, and a sandbox in Gina's backyard are shown in the diagram.

Archy [21]

Let us suppose the distance between the sandbox and garden is x feet.

Apply the sine law in the given triangle, we have

$\frac{x}{\sin 65^{\circ}}=\frac{36}{\sin 104^{\circ}}\\
\\
\text{On coss multiplying, we get}\\
x\sin 104^{\circ}=36\sin 65^{\circ}\\
\\
x=\frac{36\sin 65^{\circ}}{\sin 104^{\circ}}\\
\\
x\approx 33.6$

Therefore, in the nearest foot, the distance between the sandbox and garden is 34 foot.

Please help! The length of a rectangle is 3 less than 4 times the width. The perimeter is 34. Find the length and width of the r

Inga [223]

Length (L): 4w - 3

width (w): w

Perimeter (P) = 2L + 2w

34 = 2(4w - 3) + 2(w)

34 = 8w - 6 + 2w

34 = 10w - 6

40 = 10w

4 = w

Length (L): 4w - 3 = 4(4) - 3 = 16 - 3 = 13

Answer: width=4, length = 13
