PIRÁMIDE A PARTIR DE DATOS ANGULARES DE SUS CARAS

We start with the horizontal base, abc, of an irregular pyramid with vertex V. It is known that from the dihedral projection, v, of its external vertex onto the base, one of the sides is seen at a certain unknown angle, while the other two sides are seen at an angle twice that of the first. It is also known that the angle AVC of one of the faces is 60º.
