question 17

Multiple Choice

Use the law of Cosines to solve the given triangle. Round your answer to two decimal places. $$a = 13 , b = 17 , c = 23$$

• A) \(A \approx 33.92 ^ { \circ } , B \approx 46.84 ^ { \circ } , C \approx 99.24 ^ { \circ }\)
• B) \(A \approx 46.84 ^ { \circ } , B \approx 46.84 ^ { \circ } , C \approx 86.32 ^ { \circ }\)
• C) \(A \approx 33.92 ^ { \circ } , B \approx 99.24 ^ { \circ } , C \approx 46.84 ^ { \circ }\)
• D) \(A \approx 99.24 ^ { \circ } , B \approx 46.84 ^ { \circ } , C \approx 33.92 ^ { \circ }\)
• E) \(A \approx 46.84 ^ { \circ } , B \approx 33.92 ^ { \circ } , C \approx 99.24 ^ { \circ }\)
