Answer:

  • b = 2.8253
  • A = 45.2°
  • C = 107.4°

Explanation:

The given sides form the given angle, so the Law of Cosines can be used to find the third side.

b = √(a² +c² -2ac·cos(B)) ≈ √7.982544072 ≈ 2.8253

The measure of angle A can be found from the Law of Sines.

A = arcsin(a/b·sin(B)) ≈ arcsin(0.71017) ≈ 45.2°

Angle C can be calculated from the other two angles.

C = 180° -27.4° -45.2° = 107.4°
