Part B: Explain how to fine the measure of segments AC and CB. You must show all your work and calculations to receive full credit.

The table shows a pattern of exponents. what is the pattern as the exponents decrease?

On traditional maps, earth is represented in a flat plane, or by euclidean geometry. however, a globe is a more accurate model that comes from elliptical geometry.how does a globe represent the fact that there are no parallel lines in elliptical geometry? the equator is not parallel to any other latitudinal lines. the north and south poles are never connected by a geodesic. the geodesics connecting the north and south poles never intersect. the geodesics connecting the north and south poles intersect at both of the poles.

Given sin28.4=.4756, cos28.4=.8796, and tan28.4=.5407 find the cos of 61.6
