Answer:
You multiply 64 and 4 or 32 by 8 and both should equal 256 grams .-.
Step-by-step explanation:
Answer:
Part I: cot(15 degrees) = cot(45 - 30)
Part II: Evaluation is below
Step-by-step explanation:
<em>Everything is done in degrees</em>
<em />
Two angles that differ by 15 degrees that is easy to evaluate is 30 degrees and 45 degrees. The cot(15 degrees) = cot(45 - 30) = 1/tan(45-30) = (1+tan45tan30)/(tan30 - tan45) = (1+ sqrt(3))/(sqrt(3) - 1)
We rationalize this by multiplying 1+ sqrt(3) in the top and bottom, getting:
(4 + 2sqrt(3))/2 = 2 + sqrt(3)
I hope this helps! :)

Answer:
h = 3*tan(62) where h is the height
Step-by-step explanation:
You basically have a right triangle. the standing man is the vertical line, the shadow is the horizontal line and the 62 degrees is the angle betweenthe horizontal line and the hypotenuse.
So, relative to the angle we have the adjacent angle and opposite. What uses those? Tangent. tan(x) = opp / adj
tan(62) = h/3
h = 3*tan(62) where h is the height
