In the diagram, O is the centre. If PQ//RS and ∠ONS = 140°, find the size of ∠POM.
In the diagram, PTR is a tangent to the centre O. If angles TON = 108°, Calculate the size of angle PTN
In the diagram, PQ//RT, QR//SU,<PQR = 48º and <RTS = x. Find the value of x.
In the diagram, O is the centre, \(\bar{RT}\) is a diameter, < PQT = 33\(^o\) and <TOS = 76\(^o\). Using the diagram, calculate the value of angle PTR.
