In the figure, PQR is a straight line and TP = TQ. Find ∠ x.

UPQ365-1

 

 

 

Solution:

            TQ and PQR are straight lines

            ∠ TQP = 1800 – 1150 = 650

            TP = TQ, TPQ form an isosceles triangle

            ∠ TPQ = ∠ TQP = 650

            PQS is a triangle

            ∠ SPQ = 1150 – 800 = 350                            

            ∠ x = 1800 – 1150 – 350 = 300
