Consider the triangle with sides a=1.6, b=2.3 and c=1.2 feet. You can use cosine theorem twice to find two unknown angles:
1.
Then you can conclude that ∠B is obtuse (because ) and m∠B=110°.
2.
.
Then you can conclude that ∠C is acute (because ) and m∠C=29°.
3. m∠A+m∠B+m∠C=180°, then m∠A=180°-110°-29°=41°.
Answer: m∠A=41° (∠A is opposite to the side a=1.6), m∠B=110° (∠B is opposite to the side b=2.3) and m∠C=29° (∠C is opposite to the side c=1.2)
