SUMMARY

The discussion centers on calculating angle PSR in triangle PST, where it is determined to be 77 degrees using the equation for the sum of angles in a triangle, which states that the total must equal 180 degrees. The calculation is confirmed as correct, with angle PSR derived from subtracting the known angles of 81 degrees and 22 degrees from 180 degrees. This confirms the validity of the approach taken to solve the problem.

PREREQUISITES
  • Understanding of triangle angle properties

Homework Statement
Find angle PSR, if PQRS is a circle and PQT and SRT are straight lines
Relevant Equations
sum of angles in a triangle = 180 degree

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