The sun is 25 degrees above the horizon. find the length of a shadow cast by a building that is 100 feet tall. round your answer to two decimal places. the length of the shadow is feet.

214.45 feet.    

Step-by-step explanation:

Please find the attachment.

Let x be the length of building's shadow.

We have been given that the sun is 25 degrees above the horizon. The length of the building is 100 feet tall.

We can see from our attachment that the length of the building is opposite side and the length of the shadow is adjacent side for the angle of 25 degrees.

Since tangent relates the opposite side of right triangle with adjacent side, so we can set an equation to find the length of building's shadow as:

Therefore, the length of shadow cast by the building is 214.45 feet.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
