Can't draw diagrams on a text editor! At its simplest you need a compass and a long tape-measure. Establish a base line of known length along the bank between two points A & B.
Measure its compass bearing. Now from Point A take a bearing as near as possible at 90º to the base line to a distinct point on the far bank - a post, tree-trunk, distinctive boulder, say. Call it Point C. As long as it's visible from B as well.
Now take the bearing from B to C. Correct the bearings to find the actual angles of triangle ABC whose base is AB, "opposite side" is AC and hypotenuse is BC. Call angle ABC, "a".
Now you have a right-angled triangle in which AC is the river's width, W.
SO: W = (AB) Tan a
You can triangulate it with a non-right triangle but I'm afraid you'll have to refer, as I would, to the text-books for the appropriate formula!
OR: go out and buy or borrow a laser range-finder!

How can you get the length of an object by using width and height?
If volume can be provided then by using width, and height length can be found
How many gallons in 1 mile of the Tennessee river?
To estimate the number of gallons in one mile of the Tennessee River, we need to know its average width and depth. The river's average width is about 1,000 feet, and the average depth is approximately 10 feet. Using these dimensions, one mile of the river (5,280 feet) would contain roughly 1.5 billion gallons of water. However, this is a rough estimate, as actual measurements can vary significantly based on specific locations and conditions.
How do you find the depth to width ratio?
Measure the depth and width using the same units. Divide the depth measurement by the width measurement.
How does perimeter relate to area?
The perimeter is equal to length + length + width + width while area is length x width. Both measurements are found by using width and length.
A rectangle has a diagonal of 10 and a length of 8. what is its width?
Using Pythagoras' theorem its width is 6 units in length.
Jean camps beside a wide river and wonders how wide it is She spots a large rock on the bank directly across from her She then walks upstream until she judges that the angle between her and the rock?
Jean can determine the width of the river by using basic trigonometry. By walking upstream until she forms a measurable angle with the rock directly across, she can create a right triangle where the distance she walked and the width of the river are the two legs. By measuring the angle and the distance she walked, she can apply the tangent function to calculate the width of the river. This method helps her find the river's width without needing to cross it directly.

What is line in trigonometry?
A line in geometry has length (and location) but no width or depth. It's not itself a trigonometrical "being" but join 3 straight lines to make a Triangle, and Hey Presto! - you have Trigonometry!
What is the average width of a river in the Amazon rainforest?

How was trigonometry used in the construction of the pyramids of Egypt?
Obviously, the pyramids have a lot to do with triangles. To find the hight, length, width, volume, angle of ascent, and surface area of the pyramids, the egyptians had to use trigonometry.

What does river width mean?
River width refers to the distance across a river from one bank to the opposite bank. It can vary significantly along a river's course due to factors such as topography, sediment deposition, and flow dynamics. Measuring the width of a river is important for understanding its hydrology, ecology, and potential for flooding. Additionally, river width can influence navigation, habitat availability, and water quality.
