Explicație pas cu pas:
BC/sinA=AC/sin B=AB/sinC
sin B=sin 60°=√3/2
sin C=sin 45°=√2/2
A=180°-(60°+45°)=75°
sin A=sin 75°=sin(30°+45°)=sin 30°cos45°+cos30°sin 45°=
=√2/2×1/2+√3/2×√2/2=√2/4(1+√3)
24/√2/4(1+√3)=24(1+√3)×4/√2=48√2(1+√3)AC/√3/2=48√2(1+√3)
AC=48√2(1+√3)×√3/2==24√6(1+√3)
AB=48√2(1+√3)×√2/2=48(1+√3)
