Solve for angle alpha and angle theta by Cosine Law. With angle alpha known you can find angle beta.
The shaded area is equal to a circular sector of radius 7 cm with central angle beta minus circular segment with of radius 14 cm with central angle 2-theta minus isosceles triangle of equal sides 7 cm with included angle beta.
