a. -sqrt5 = r cos (theta -27degrees)

b. sqrt5 = r cos (theta -27degrees)

c. -sqrt5 = r cos (theta +27degrees)

d. sqrt5 = r cos (theta +27degrees)

is the answer c.

**Reiny**, Monday, September 6, 2010 at 1:54pmmy polar equation would be

2rcosŲ + rsinŲ = 5

r(2cosŲ + sinŲ) = 5

r = 5/(2cosŲ + sinŲ)
