    Stuck Triangle
AI Thread Summary
The discussion revolves around solving for the sides a and b of a triangle given its height and base. The user has established equations using the Pythagorean theorem and the Geometric Mean theorem, resulting in three equations with three unknowns: a, b, and e. There is uncertainty about whether the angle between sides a and b is 90 degrees, which could affect the approach to solving the problem. The user seeks clarification on the complete problem to proceed effectively. The conversation emphasizes the need for a clear understanding of the triangle's properties to find the unknown sides.

I have figured out the triangle's height and base, but I need to figure out sides a and b. I have tried Pythagorean theorem and similar triangle ratios, but it is not working out. Please help. See picture below. Thank you.View attachment 6489

We have that two right triangles and from the Pythagorean Theorem for those two we get:
$$464^2+e^2=a^2$$ and $$464^2+(1218-e)^2=b^2$$

From the Geometric mean theorem we have that $$464^2=e\cdot (1218-e)$$

Now we have three unknown variables, $a,b,e$, and three equations. So, we can find the values for $a,b,e$.
 
Is the angle contained by $a$ and $b$ equal to $90^\circ$? For that matter, what is the complete problem?
 
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...
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...
