Answer:
∠B = 36.87
Step-by-step explanation:
Since you are trying to find the angle measurement, you must use the inverse of cosine: 
(you're using cosine because you have the opposite side and adjacent side):
≈36.87
If you divide 61 by 66, you will get .9242424. The thousandths place is the third number, so you base it off of the four number. If the fourth number is under 5, the third number stays the same and all numbers after it disappear. If the number is above 5, the third number rounds up 1 and the rest disappear. Because the 3rd number is 4 and the 4th number is 2, you will get the answer of .924
