Rhomboid

The dimensions of the rhomboid sides are a= 5cm, b = 6 cm and the size of the angle at the vertex A is 60°. What is the length of side AC?

Correct result:

|AC| =  6.65 cm

Solution:

sinγsin60=56 γ=arcsin.72168 γ=46.194 β=1806046.194=73.806 AC6sin73.806sin60 AC=61.1088853 AC=6.6533121 cm6.65 cm
