Multiple Choice

Solve the right triangle. If two sides are given, give angles in degrees and minutes.
- $$\mathrm { a } = 3.9 \mathrm {~cm} , \mathrm {~b} = 1.2 \mathrm {~cm} , \mathrm { C } = 90 ^ { \circ }$$
Round values to one decimal place.

• A) \(\mathrm { A } = 17.9 ^ { \circ } , \mathrm { B } = 72.1 ^ { \circ } , \mathrm { c } = 5.1 \mathrm {~cm}\)
• B) \(\mathrm { A } = 72.9 ^ { \circ } , \mathrm { B } = 17.1 ^ { \circ } , \mathrm { c } = 4.1 \mathrm {~cm}\)
• C) \(\mathrm { A } = 68.4 ^ { \circ } , \mathrm { B } = 21.6 ^ { \circ } , \mathrm { c } = 4.1 \mathrm {~cm}\)
• D) \(\mathrm { A } = 17.1 ^ { \circ } , \mathrm { B } = 72.9 ^ { \circ } , \mathrm { c } = 4.1 \mathrm {~cm}\)
