Answer
If you would like it in numbers it would be 16.970562748
Given:
In triangle MNO, angle ONM is a right angle. Angle NOM is 40 degrees and angle LMN is 50 degrees.
To find:
The value of cos(M).
Solution:
In a right angle triangle,

Draw a diagram using the given information.
In triangle MNO, angle ONM is a right angle so its opposite side MO is the hypotenuse. For vertex M, MN is the base of the triangle. So,

Therefore, the correct option is B.
Answer:
c

Answer: 200.96 ft^2 (choice C)</h3>
=======================================================
Work Shown:
A = pi*r^2
A = 3.14*8^2
A = 200.96
Note that the radius r = 8 is half of the diameter d = 16. I'm using the approximation pi = 3.14, which means the area is approximate. To get a more accurate answer, use more decimal digits of pi. The units of the area are in square feet, which can be written as "sq ft" or as "ft^2".
