This forum is not for lazy students who don't want to do their homework and we are not supposed to do it for them. So I gave a hint only. With that hint you can solve the problem without any thought about geometry. It's a 4 line mathematical rearrangement.SonyAD said:
It's and excellent one! I will admit that for a moment I forgot that the smaller right triangle had both legs of length xSonyAD said:

There is nothing intuitive about the need for new sketches and a length derivation. Also you fail the exam by running out of time if you solve the tasks much more generally than needed.SonyAD said:
What solution? Your entire contribution to this thread was "What sort of hint is that?"SonyAD said:
In this problem it is. Gerunuk gave a hint to solve this problem.
Hints are all you'll get here, I'm afraid. If this question is from an entrance exam, and a student doesn't know how to do problems like these, then he/she shouldn't belong to the program/school/course he/she is entering?yaseen shah said:
It took me 6 lines, not 4, but I tend to write more steps than probably what is necessary.Gerenuk said:
69The tangent of an angle is the ratio of the length of the opposite side to the length of the adjacent side in a right triangle.
The value of tan[theta] can be found by using a scientific calculator or by using the trigonometric function tables.
The range of values for tan[theta] is from negative infinity to positive infinity, as it is a continuous function.
Yes, the value of tan[theta] can be negative depending on the value of the angle theta. For example, if theta is in the second or fourth quadrant, the tangent will be negative.
Tan[theta] is used in various fields such as engineering, astronomy, and geography to calculate distances, heights, and angles. It is also used in navigation and surveying to determine the direction and location of objects.
