Answer:
When you see a formula like this, try to operate, so you will see some identities sooner or later. In this case, we have a substraction identity:
\frac{cos ( \alpha - \beta )}{cos \alpha cos \beta } = \frac{cos \alpha cos \beta + sin \alpha sin \beta }{cos \alpha cos \beta } = 1 + tan α · tan β

Answer:
55.5 B
Step-by-step explanation:
We have the following points of data
48, 49, 50, 51, 54, 55, 56, 58, 60, 62, 63, 63
The median is the data point in the middle (when listed in order)
If we find the middle number we'll see that it's between 55 and 56. When this is the case you find the average of the two numbers (add them and divide by 2)
(55+56)/2=55.5
