MHB Solve Right Triangle Problem Without Knowing Bottom Line

AI Thread Summary
To solve a right triangle problem without knowing the base length, one can use trigonometric relationships involving angles. The angle θ can be utilized to find the hypotenuse (d) with the formula d = 16/cos(θ), where 16 meters is the adjacent side. The discussion raises skepticism about the possibility of determining a numerical value for d with only the angle θ provided. Clarification is sought on how one could arrive at a solution without additional information. Understanding these trigonometric principles is essential for solving similar problems effectively.

How would I have to calculate this question for an answer, a friend of mine told me he could get the answer without knowing that the bottom line was 16 meters, I can't seem to find a way that would work, I am not sure if I am missing something or he is lying.

I'd also like to know how your friend could determine a numerical value for $d$ just knowing the angle $\theta = 0.19$ with no other information.
If he let's you know how, post back and enlighten me.

Using the angle, $\theta$, value and the 16 meters ...

$\cos{\theta} = \dfrac{16}{d} \implies d = \dfrac{16}{\cos{\theta}}$
 

Thread 'Non-orthogonal bases'

Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
