A surveyor is attempting to calculate the distance between earth and sun (L) during a solar eclipse, as shown schematically in Figure 3.1, assuming values of only these parameters are given: the angle g, the moon diameter d, and the sun diameter D. (a) Discuss, show and prove numerically and graphically whether these 3 parameters are adequate for this calculation? (b) Are there any other requirements such as the type or any other conditions for the solar eclipse? (c) Calculate the ratios D/d and L/Zand discuss whether there are any correlations between them. (d) Find values of the distance between sun and earth (L), sun and moon (4) and earth and moon EM =/, when assuming the diameter of the moon is d = 3,474 km, diameter of the sun is D = 1,391,400 km, and the angle
