Question

If TP and TQ are two tangents to a circle with centre O, so that ÐPOQ = 100° then ÐPTQ is equal to (A) 100° (B) 50° (C) 60° (D) 200°

Answer 1

Answer:

Step-by-step explanation:

angle sum property of a quadrilateral,

∠t + ∠p + ∠ q + ∠o = 360°

90° + 90° + 100° + ∠o = 360°

∠o = 360° - 280°

∴∠o = 80°

your options are wrong!!!!

Answer 2

ans = 80

but this is not available in options please consider
