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?

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?

You want to swim straight across a river that is 76 m wide. You find that you can do this if you swim at an angle of θ = 28° from the upstream direction at a constant rate of 1.5 m/s relative to the water. At what rate does the river flow? The angle θ is measured from the river bank (directly upstream is θ = 0° while directly across the river is θ = 90°).

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.)

Q1. Jim stands beside a wide river and wonders how wide it is. He spots a large rock on the bank directly across from him. He then walks upstream 65 strides and judges that the angle between him and the rock, which he can still see, is now at an angle of 30° downstream Jim measures his stride to be about 0.8 m long. Draw a diagram. Estimate the width of the river.
