In the diagram above, PQR is a straight line and PS is a tangent to the circle QRS with /PS/ = /SR/ and ∠SPR = 40o. Find ∠PSQ
A
40o
B
30o
C
20o
D
10o
correct option: a
R = P (base ∠s of isc Δ, ps = RS)
∴R = 40o
∠PSQ = R (∠s in alternate segment)
∴∠PSQ = 40o
∴R = 40o
∠PSQ = R (∠s in alternate segment)
∴∠PSQ = 40o
