Answer:

Step-by-step explanation:

To dilate is to make something bigger. It says in the question that you dilate by a factor of 2, so multiply the length of the side by 2. This will get you 68.

As far as angles are concerned, angles do not change when the object is scaled bigger. So for the angle of A, the answer is still 28 degrees.

This leaves us with our final answer, which is B.

Percent change=change/original times 100

change=75 to 25 or 75-25=50

so

percent change=50/75 times 100=0.6666666 times 100=66.66666%

The angle of elevation to the top of a building in chicago is found to be 11◦ from the ground at a distance of 1000 feet from th

erastova [34]

The height is 1943.8 feet. easiest way to do this is draw a little diagram. Draw the building and the unknown height can be "x". We know a 1000 feet away from the base of the building, the angle between the ground and top of the building is 11 degrees. If you draw this, you can see that you can use the tan function to find the missing "x". tan (angle) = opposite side/adjacent side. So tan(11) = x/1000. Isolate for x and you get 1943.8 feet
