Satellites One of the smallest space satellites ever developed has the shape of a pyramid. Each of the four faces of the pyramid is an equilateral triangle with sides about 13 cm long. What is the area of one equilateral triangular face of the satellite? Round your answer to the nearest whole number. 73 cm2 ng 52. Area 35. The apothem is 1 to a side of the pentagon. Two right A are formed with the radii of the pentagon. So the A are e by HL. Therefore the A formed by the apothem and radii are by CPCTC, and the apothem bisects the vertex L.
