w=125/(cotA+cotB)
I can't really help you... but I know who can! I can't submit the URL but google the question and it should be at the top as a youtube video, hope this helps.
You have a nice equation. Is there something we're supposed to do with it?
As I recall, w represents the width of a river, and you have the angles at A and B. What is there that you cannot do? Just plug in the values of A and B, and the evaluate the numbers to get w!
fine. thanks by the way steve.
thanks for the suggestion sockmaster (opinion based answers)
To understand how to obtain the value of w, let's break down the equation step by step.
First, let's simplify the expression within the parentheses, (cotA + cotB). The cotangent of an angle A is defined as the ratio of the adjacent side to the opposite side of a right triangle. Similarly, the cotangent of an angle B is the ratio of the adjacent side to the opposite side of a different right triangle.
To find the cotangent of angle A, we need the values of the adjacent and opposite sides. Similarly, for angle B, we also need the values of the adjacent and opposite sides. Without these values, we cannot directly calculate cotA or cotB.
If you have the lengths of the adjacent and opposite sides of angles A and B, you can calculate the cotangent of each angle using the formula cotA = adjacent/opposite and cotB = adjacent/opposite.
Once you have the values of cotA and cotB, you can substitute them back into the equation:
w = 125/(cotA + cotB)
Now, you can calculate the sum of cotA and cotB and substitute it into the equation to find the value of w.
It's important to note that without knowing the lengths of the adjacent and opposite sides of angles A and B, we cannot determine the values of cotA and cotB, and ultimately, the value of w.
