Exercise - 10.2 (( class-10, maths ))
Question-2.
It is given that TP and TQ are tangents.
Therefore, radius drawn to these tangents will be perpendicular to the tangents.
Thus, OP _l_ TP and OQ _l_ TQ
angle OPT = 90°
angle OQT 4 90°
◇In quadrilateral POQT,
Sum of all interior angles = 360°
OPT + POQ + OQT + PTQ = 360°
=> 90° + 110° + 90° + PTQ = 360°
=> 290° + PTQ = 360°
=> PTQ = 360° - 290°
=> PTQ = 70°
☆ Hence, angle PTQ is 70° .
