History

The puppy runs 34 feet, approximately.

Step-by-step explanation:

The problems models two triangles, the right triangle can be solved using trigonometric reasons and the other triangles can solved using law of cosines.

The distance that the puppy is running comprehend a side of the first triangle, however before finding that side, we need to first find the longest side, which is from the top of the electrical post to bench, which comprehend the hypothenuse of the bigger right triangle.

Applying trigonometric reasons, we have

$cos57=\frac{40}{x}\\ x=\frac{40}{cos57} \approx 73$

This is the longest hypothenuse.

$cos34=\frac{40}{y}\\ y=\frac{40}{cos34} \approx 48$

This is the common side, which goes from the top of the electric pole to the fire hydrant.

Now we know the common side between triangles and the longest hypothenuse, we use the law of cosines to find the side that comprehend the distance covered by the poppy

$d^{2}=x^{2}+y^{2}-2.x.y.cos23\\\\d^{2}=(73)^{2}+(48)^{2}-2(73)(48)cos23\\d=\sqrt{1182} \\d\approx 34$

Therefore, the puppy runs 34 feet, approximately.
