Not sure the type of answer you are looking for. Yet 270 degrees is 3/4 of a full turn. (90 x 3)
Therefore you could state 3/4 of a turn. Also, 1/4 of a clockwise turn would work.
I think C would be for number 11
A is for 12.
x/2 < - 18
Assuming that is 2 right triangles sharing a side
height^2 = 20^2 -7^2
height^2 = 400 - 49
height^2 = 351
height =
<span>
<span>
<span>
18.7349939952
</span>
</span>
</span>
x^2 = 24^2 - <span>18.7349939952^2
x^2 = 576 -351
x^2 = 225
x = 15

The total number of pencils is 2,160. When estimating to the nearest hundredth one gets 2,200, which is an underestimate.
The advantage of underestimating is that your answer is more accurate than an overestimate.
