Abigail at point A is 10 m from Baron at point Band 8 m from Chin at point C. Baron measures the angle between his line of sight to Abigail and his line of sight to Chin to be 48°. What is the distance between Baron and Chin? Express your answer accurate to 1 decimal place.

In the final seconds before the plane landed in the Hudson, the pilot slowed the plane.  While the plane slowed it climbed from 210 ft at 3:29.58 to 370 ft at 3:30.17. An elevation change of 160 ft over a distance of 2000 ft. What was the angle of ascent for the plane (e) as it slowed? Round your answer to the nearest hundredth (second decimal place).

9. A surveyor is mapping a large marsh in a state park. He walks and measures a straight line south from a cliff for 0.75 mile to a large tree. He walks east, but he has to make a detour around the marsh. He gets around the marsh to a spot where he is perpendicular to the large tree and the trail he originally walked south on. He looks northwest and measures a 40° angle (ZA) northwest to the cliff from his line of sight to the large tree. He measures the distance back to the starting point at the cliff as 1.17 miles. What is the straight-line distance from the large tree east to ZA? What is the tangent of ZB , the angle at the cliff? Clff 0.75 mile 1.17 mile 40 Tree

To determine the angle of elevation of a star in the sky, you align the star and the top of the backboard of a basketball hoop that is 5ft higher than your eyes in your line of vision. Your horizontal distance from the backboard is 12 feet. What is the angle of elevation of the star?
