math questions:/ can anyone help?:/ MEDAL! :/

Answer 1

At an altitude of 12,000 ft, a pilot sees two towns through angles of depression of 37° and 48°. To the nearest foot, how far apart are the towns?

Answer 2

An observer in a plane 2500 m high sights two ships below. The angle of depression to one ship is 32°, and the angle of depression to the other ship is 44°. How far apart are the ships?

Answer 3

Find the two angles that satisfy the following equation.
Sin (3x - 1) = Cos (2x +1)?

Answer 4

In the support structure for the Ferris wheel, m<CAB = 30°. If AB = AC= 27ft, find BC.

Answer 5

A bicycle race follows a triangular course. The three legs of the race are, in order, 2.3 km, 5.9 km, and 6.2 km. Find the angle between the starting leg and the finishing leg to the nearest degree.

Answer 6

ill give you a medal:/

Answer 7

For the first one, you can use knowledge of right angles to find the values of the angles inside the triangle (53 on the T1 side, 42 on the T2 side). Then you can use trigonometry with a right triangle (sohcahtoa) to find length of the base of the triangle.

Answer 8

You use the same strategy on the second one to find the base of the triangle. But here, you want to subtract the answer you get (in the first one you added them).



You can find y and z with trig. x = z - y
