Cot(theta) is the one that works best for this problem
1 more quart; 4 quarts is 1 gallon, so 2 quarts is 1/2 gallon.
Answer:
36
Step-by-step explanation:
is made up of s + r, and since r is 
of we know r must be the remaining 
of .
We can solve for by using this equation:
1. 2 fifths of is 24
2. multiply both sides by 
to isolate
3. is 60°
We can now solve for r
1. the equation the problem gave us
2. substitute for 60 (we solved for it before)
3. 
is 36°
