Use the cofunction and reciprocal identities to answer the question.Given that sin 40° = 0.6428 and cos 40° = 0.7660, find the six function values of 50°.
A. sin 50° = 1.305; cos 50° = 0.7660; tan 50° = 1.192
csc 50° = 0.6428; sec 50° = 1.556; cot 50° = 0.8391
B. sin 50° = 0.7660; cos 50° = 0.6428; tan 50° = 1.192
csc 50° = 1.305; sec 50° = 1.556; cot 50° = 0.8391
C. sin 50° = 0.6428; cos 50° = 0.7660; tan 50° = 1.192
csc 50° = 1.556; sec 50° = 1.305; cot 50° = 0.8391
D. sin 50° = 1.305; cos 50° = 0.7660; tan 50° = 1.192
csc 50° = 1.556; sec 50° = 0.6428; cot 50° = 0.8391
