Answer:
Supplimentry
Step-by-step explanation:
Answer:
4 friends evenly divided up a n -slice pizza.
So, the number of slices each friend received = n/4
Now, Harrison ate 1 fewer slice than he received. As he received n/4 slices, so 1 fewer than n/4 means......
Harrison ate n/4-1 slices of pizza.
Step-by-step explanation:
is in quadrant I, so
.
is in quadrant II, so
.
Recall that for any angle
,

Then with the conditions determined above, we get

and

Now recall the compound angle formulas:




as well as the definition of tangent:

Then
1. 
2. 
3. 
4. 
5. 
6. 
7. A bit more work required here. Recall the half-angle identities:



Because
is in quadrant II, we know that
is in quadrant I. Specifically, we know
, so
. In this quadrant, we have
, so
