In triangle ABC, AC = 1, angle A = 30 degrees, and angle B = 15 degrees.  What is the length of side AB?

Obtuse scalene triangle.
When you know the 3 angles and one side, then use The Law of Sines to calculate the other 2 sides.
Sides: BC= 1.932 AC = 1 AB = 2.732

 

Area: T = 0.683
Perimeter: p = 5.664
Semiperimeter: s = 2.832

 

Angle ∠ A = α = 30° = 0.524 rad
Angle ∠ B = β = 15° = 0.262 rad
Angle ∠ C = γ = 135° = 2.356 rad
