Halley's Cornel has an elliptical orbit with the Sun at one focus. Its orbit, shown in the figure below, is given approximately by
'
In the formula, r is measured in astronomical units. (One astronomical unit is the average distance from Earth to the Sun. approximately 93 million miles.) Use the given formula and the figure to solve Exercises 29-30. Round to the nearest hundredth of an astronomical unit and the nearest million miles.

Here is a more modern method From a satellite 600 mi above the earth it is observed that the angle formed by the vertical and the line of sight to the horizon is 60.276. Use this information to find the radius of the earth.arrow_forwardOn a baseball diamond a square, the bases are 90ft apart. Use the Law of Sines to find the distance from home plate to second base.
