A surveyor measures the distance across a straight river by the following method: Starting directly across from a tree on the opposite bank, he walks x = 102 m along the riverbank to establish a baseline. Then he sights across to the tree. The angle from his baseline to the tree is θ = 39.0°. How wide is the river?

To find the distance across a river, a surveyor chooses points A and B, which are x = 500 ft apart on one side of the river (see the figure). She then chooses a reference point C on the opposite side of the river and finds that ∠BAC ≈ 82° and ∠ABC ≈ 52°. Approximate the distance from A to C. (Round your answer to the nearest foot.)
plz explain steps. To find the distance across a river, a surveyor chose points A and B, which are 246 feet apart on one side of the river. She then chooses a reference point Con the opposite side of the river and finds that BAC is about 81° and ZABC is about 480. A 246 feet B 870 480 NOTE: The picture is NOT drawn to scale. Round all answers to 3 decimal places. The distance from point A to...
please show steps. To find the distance across a river, a surveyor chose points A and B, which are 184 yards apart on one side of the river. She then chooses a reference point on the opposite side of the river and finds that ZBAC is about 83° and ZABC is about 48º. A 184 yards B 83° 480 C NOTE: The picture is NOT drawn to scale.

A topographer calculates the width of a river by the following method: It stops directly in front of a tree on the opposite side and walks 100 m along the river bank, then looks at the tree. The angle formed by the line that starts from it and ends in the tree is 35 °. What is the width of the river? (Solve the problem using the analytical method of vector addition) a)29.9 b)142.8 c)70.1 d)110.5
Suppose at one point along the Nile River a ferryboat must travel straight across a 1.08-mile stretch from west to east. At this location, the river flows from south to north with a speed of 2.85 m/s. The ferryboat has a motor that can move the boat forward at a constant speed of 26.0 mph in still water. If the captain points the boat directly at the target location on the east bank of the river, how far downstream will...
A ranger wants to determine the height of a tree across a river. The angle of elevation from the bank is 43°. When she walks back from the bank 27 feet, she determines that the angle of elevation is 32°. How tall is the tree? Round your answer to the nearest foot. Enter your answer here:
