A flagpole 25 ft high, standing on the edge of the roof of a high building, when seen from a point A on the ground subtends an angle of 3°50’. If A is 200 ft from the bottom of the pole, how far is it from the top?
As seen from a point P, one end A of an island is 4 miles away and the other end B is 1 mile away. The island subtends at P and angle of 110°. Find the length of the island.

Two points, A and B, are separated by an obstacle. The straight line DAC is run making AC = 550 ft and AD = 1100 ft. The angle BCA is found to be 57° and angle BDA to be 47°. Find the distance AB.
As seen from a point P, one end A of an island is 4 miles away and the other end B is 1 mile away. The island subtends at P and angle of 80°. Find the length of the island.
A road 9 miles long runs from a point P to a point O on a straight beach, making an angle of 32° with the beach. Two other straight roads, each 6 miles long, lead from P to the beach. How far is it from O along the beach to the nearer of these?
The earth is approximately 92.9 million miles from the sun, and 240,000 miles from the moon. When the angle sun-earth-moon is 25°, how far is the moon from the sun?
In order to obtain the distance from a point A to an inaccessible point B, a base line AC and the angles A and C were measured. If AC = 800 ft, A = 46°, C = 38°, find AB.
A connecting of rod 24 inches in length is attached at Q to a drive wheel whose radius is 6 in. when OP, the distance from P to the center of the wheel, is 26 inches, find the angle QOP.
A mountain is seen in a direction 30° north of east and is known to be 5 miles away from another mountain as seen in a direction 40° north of east 8 mile distance. how far apart are the two?
