∠A = 28°, a = 10.5 m, b = 15.0 m

Does this triangle fit the "ambiguous case" and which explanation is best?

• no, because only one triangle exists for all measurements

• no, because the known angle corresponds to the shorter length

• yes, because the known angle corresponds to the shorter length

• yes, because length b could be the hypotenuse of a right-angled triangle
