Question

If TP and TQ are two tangents to a circle with centre O so that ∠POQ=1100

,find ∠PTQ.

a) 600

b) 700

c) 800

d) 900​

Answer 1

Answer:

according to me measure of PTQ must be 70

Step-by-step explanation:

the point on which tangents meet circle is of 90⁰

so angle OPT and angle OQT are of 90

Now POQT is a quadrilateral so sum of all angles is 360

therefore PTQ= 360-(110+90+90)

= 360 - 290

= 70
