Michele wanted to measure the height of her school's flagpole. she placed a mirror on the ground 48 ft from the flagpole, then walked backwards until she was able to see the top of the pole in the mirror. her eyes were 5ft about the ground and she was 12 ft from the mirror. using similar triangles what is the height of the flag pole

20 ft

Step-by-step explanation:

Let the height of flag pole be x.

From the question, we can see there is a directly proportional relationship between the height and distance because they are making similar triangles such that

Hence, the height of flagpole = 20 ft.

d 192

step-by-step explanation:

we find our area to find area we multiply thoses numbers to get our answer so our area is 192

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
