In the above figure, PQR is a straight line and `anglePQS: angleSQR=7 – InterviewSolution

1.	In the above figure, PQR is a straight line and `anglePQS: angleSQR=7:5`. Find `angleSQR`.
Answer» Correct Answer - D Let `anglePQS and angleSQR` be `7x^(@) and 5x^(@)`, respectively. `anglePQS +SQR=180^(@)( :. "PQR is a straight line. ")` `7x^(@)+5x^(@)=180^(@)` `x^(@)=15^(@)`. `angleSQR=5x^(@)=75^(@)` Hence, the correct option is (d)
