AI Thread Summary
In triangle PST, angle PSR is calculated as 180 degrees minus the sum of the other two angles, which are 81 and 22 degrees, resulting in PSR being 77 degrees. The discussion confirms that this calculation is correct based on the principle that the sum of angles in a triangle equals 180 degrees. The context involves a circle with points PQRS and straight lines PQT and SRT. The approach to finding angle PSR adheres to the relevant geometric equations. The conclusion affirms the accuracy of the calculation.

From triangle PST, angle PSR = 180-(81+22)
=77 degrees sum of angles in triangle.
Is my attempt correct?

Looks good to me.
 

Thread 'Finding the number of ways to arrange identical balls in a circle (3 different colors)'

I tried to combine those 2 formulas but it didn't work. I tried using another case where there are 2 red balls and 2 blue balls only so when combining the formula I got ##\frac{(4-1)!}{2!2!}=\frac{3}{2}## which does not make sense. Is there any formula to calculate cyclic permutation of identical objects or I have to do it by listing all the possibilities? Thanks

Thread 'Greatest possible value of a constant in polynomial'

Since ##px^9+q## is the factor, then ##x^9=\frac{-q}{p}## will be one of the roots. Let ##f(x)=27x^{18}+bx^9+70##, then: $$27\left(\frac{-q}{p}\right)^2+b\left(\frac{-q}{p}\right)+70=0$$ $$b=27 \frac{q}{p}+70 \frac{p}{q}$$ $$b=\frac{27q^2+70p^2}{pq}$$ From this expression, it looks like there is no greatest value of ##b## because increasing the value of ##p## and ##q## will also increase the value of ##b##. How to find the greatest value of ##b##? Thanks
