the angles are ... 45º , 60º , 75º
the sides are in the same ratio as the sines of the angles
k[sin(45º) + sin(60º) + sin(75º)] = 13.3 cm
solve for k (the constant of proportionality)
... k times the sine of an angle gives the length of the opposite side
Draw a trianglw whose perimeter is 13.3 cm and base angles are 45 degree and 60 degree
