The Problem

a) Danielle is due east from an oak tree. Danielle is looking at Andrew at a bearing of S32W. Andrew is looking at the same oak tree with a bearing of N15E. Andrew is also 52 feet away from the oak tree. How many feet apart are Andrew and Danielle?

b) Andrew and Danielle are now together and they decide to go on a date. They go on a date and now it is time to part. They leave from the same point. Their paths diverge by a bearing of 088 degrees. If Danielle walks for 2.7 miles and Andrew walks for 3 miles, how far apart are they at this time?

WPP #12: Unit O Concept 10: Angles of Elevation and Depression

http://gomighty.com/wp-content/themes/gomighty/lib/goal_images/files/Hot-Air-Balloon.jpg

The Problem

a) Andrew is at ground level and measures the angle of elevation to the hot air balloon to be 37*. If, at this point he is 57 feet away from the hot air balloon, what is the height of the hot air balloon from the ground? (round to the nearest foot)

b) Andrew is now in the hot air balloon and measures the angle of depression which is 25*. Andrew knows that he is 240 feet high up in the air than the base of the forest. How far away horizontally is Andrew from the forest? (round to the nearest foot)
