Jordan and Missy are standing together in a schoolyard. Jordan, who is 6 feet tall, casts a shadow that is 54 inches long. At the same time, Missy casts a shadow that is 45 inches long. How tall is Missy?

You have 2 similar triangles, so use ratios

6 feet/54 inches = h feet/45 inches

54h feetinches = 270 feetinches

h = 270/54

= 5

Missy is 5 feet tall.

no

explanation:

since the earth is flattened at the poles and bulges at the equator, geodesy represents the figure of the earth as an oblate spheroid. the oblate spheroid, or oblate ellipsoid, is an ellipsoid of revolution obtained by rotating an ellipse about its shorter axis.

reflecting point a across the origin negates both of its coordinates.

b = (5, -4)
