Answer:
<BOC = 100*
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

8. 
L = W + 55
2L + 2W = 4242
L + W = 2121
(W + 55) + W = 2121
2W + 55 = 2121
W = 1033 inches L = 1088 inches
