(a) As illustrated in the accompanying figure, suppose that an archaeologist standing at the center of a side mea- sures the angle of elevation of the apex to be = 51° with an error of ±0.5°. What can the archaeologist reasonably say about the height of the pyramid? (b) Use differentials to estimate the allowable error in the elevation angle that will ensure that the error in calcu- lating the height is at most ±5 m. 230 m 230 m

63. The base of the Great Pyramid at Giza is a square that is
230 m on each side.
(a) As illustrated in the accompanying figure, suppose that
an archaeologist standing at the center of a side mea-
sures the angle of elevation of the apex to be = 51°
with an error of ±0.5°. What can the archaeologist
reasonably say about the height of the pyramid?
(b) Use differentials to estimate the allowable error in the
elevation angle that will ensure that the error in calcu-
lating the height is at most ±5 m.
