Multiple Choice

Solve the triangle.
- $$\mathrm { b } = 20 , \mathrm { c } = 28 , \mathrm {~A} = 81 ^ { \circ }$$

• A) \(\mathrm { a } \approx 34.3 , \mathrm {~B} \approx 38.5 ^ { \circ } , \mathrm { C } \approx 60.5 ^ { \circ }\)
• B) \(\mathrm { a } \approx 34.3 , \mathrm {~B} \approx 42.5 ^ { \circ } , \mathrm { C } \approx 56.5 ^ { \circ }\)
• C) No triangles possible
• D) \(\mathrm { a } \approx 31.8 , \mathrm {~B} \approx 38.5 ^ { \circ } , \mathrm { C } \approx 60.5 ^ { \circ }\)
