The edge of the floor of the regular triangular prism isa. The slant side gamma one side of which is against the floor edgeaand the other side which crosses the point M, forms the angle alfa. The point M divides the edge of the side as 3:5, beginning from the bottom floor. Declare and calculate the area of the slant gamma and the relation of the parts of the prism.

alfa = 30 degrees

a = 10 cm
