Step-by-step explanation:
The sum of the interior angles of this triangle must be 180 degrees.
Thus, angle x is 180 degrees less (39 degrees plus 125 degrees), or
x = 180 degrees - 164 degrees = 16 degrees.
Because of the 125 degree angle, this is an obtuse triangle.
We add all these mixed numbers together:
1 1/2 + 2 3/4 + 2 1/3
It will be easier to convert the mixed numbers into improper fractions:
3/2 + 11/4 + 7/3
Now we have to find the common denominator which is 12:
18/12 + 33/12 + 28/12 = 79/12 = 6 7/12
The answer is 6 7/12 hours.

Answer:
B. 91
Step-by-step explanation:
14C12 = 14!/(12!(14-12)!) = 14·13/(2·1) = 7·13 = 91
