Answer:

10.11, if TP and TQ are the two tangents to a circle with centre O so that ∠ POQ = 110°, then ∠ PTQ is equal to. (A) 60° (B) 70° ... Reason : Radius and tangent are perpendicular to each other. Thus ∠OPQ is a right angle.

Answer:

angle PTQ = 70

The tangent makes right angle at the point of contact

therefore angle OPT = 90 and angle OQT =90

Now ,

angleOPT+ angleOQT+ anglePOQ+anglePTQ =360°

90°+90°+110°+anglePTQ =360°

290°+ anglePTQ =360°

anglePTQ =360° - 290°

anglePTQ =70°
