(2) 5.6 A surveyor measures the zenith angle from the cemetery on Rondebosch Common to the top of Devil's Peak at 7650'20". She then moves 2 km closer (horizontal distance), to Jammie Plaza, and measures zenith angles to Devils' Peak and the same cemetery, as 680550 and 923005" respectively. Assuming the cemetery is at sea level, calculate the height above sea level of Devil's Peak from the surveyor's observations. (6)
