A glass window, shown in Figure 1 , is located at \( 30^{\circ} \) South latitude, is \( 4 \mathrm{~m} \) high and 10 \( \mathrm{m} \) wide and is facing East. On 20 April at \( 11 \mathrm{am} \), determine: a. the Solar Altitude and Solar Azimuth Angles, [1 mark] b. the area fraction ( \( = \) Ashading \( / \) Awindow) of the shading from the top and \( \quad[1 \) mark] c. the area fraction of the shading from the side.
