Answer:
30/75 2/5
Step-by-step explanation:
there are 30 shaded squares, and a total of 75 squares. Therefore the fraction is 30/75. This can be simplified to 2/5 if both sides are divided by fifteen.
To make a percentage, simply divide 2 by 5 which equals 0.4 = 40%
The cotangent function can be obtained by taking the reciprocal of the tangent of the same angle. Using a calculator, taking the tangent of 10 degrees and taking the reciprocal of the answer would yield the correct one. With that, the correct answer would be D.) 5.671.
I believe the answer is
26
sorry if wrong
if not an answer choice then 168.
it is b.9 because u have to multiply (w×h×l)/3
