Answer:The ball dropped 56 feet after 3 seconds
Step-by-step explanation:
It should be 100 because it has to add up to 180 and 50+30=80 so the third angle must be 100
Three equivalent fractions would be 1/4 2/8 4/16
Since the sample is 1/25 the size and the size of the sample is 1m then:

x is the height of our container. we need to move 1/25 to the other side so we multiply both sides of the equation by 25.

On the right side of the equation, 1/25 cancels out with 25 since:

so we are left with the 25 x 1 on the left:

so the container is 25m; C.
