Thus 9 W 25 WW 20 W x and therefore the requested acreage is 25 20 divided by 9, or 500/9 which is 55 and 5/9 acres. On the other hand, if we know the ratio of areas and the side of one of the figures, we can determine the length of the side in the second figure. S. Silverberg Fig. 4 If a plot with one side measuring 3 inches represents 20 acres of land, what is the area of a similar figure with the corresponding side equal to 5 inches? the first field contains 2 acres, and the second field contains 5 acres.
19 Solution by sector. The known angle (the complement of the latitude) and its (known) opposite side (the declination) form the leg and the base of the smaller of the two similar isosceles triangles of the sector. The known angle (the right angle) and its (unknown) opposite side (the rising amplitude) form the leg and the base of the larger similar isosceles triangle 46° 49' N 10° 20° 23° 30' 30° 40° 50° 60° 90° 20° 12' N Azimuth = 28° 16' North of East Fig. 20 Solution by Gunter’s Scale.

In a very real sense, the mathematics of the heavens was brought down to the realm of earthly concerns and endeavors. Immediately following this period a second revolution in trigonometric applications was ushered in by the invention of logarithms by Napier (1614, 1618) and the rapid development of tables of the logarithms of both natural numbers and trigonometric values by Napier and Briggs (1619) and others.
