95% of a normal distribution lies within ±1.96 standard deviations of the mean. That is, ±3 years represents ±1.96 standard deviations, so ...
.. the standard deviation is 3/1.96 = 1.53 years.
Answer:
1: 98
2: 82
3: 98
4: 82
Step-by-step explanation:
So 2 is 82deg then the opposite is also 82 so 4 is 82deg
Then 82+82 = 164deg, and we remain with 360deg-164deg which is = 196.
Since the other two angles will be equal (they are opposite each other) we can decide 196/2 = 98
So 3 and 1 are 98deg
