o from point I outside the circle at Point P & Q on the circle
& TP = 7cm then what is length of TQ ? Give reason​

Answer 1

Answer:

Answer 2

Answer:

Given, ∠POQ=110

∘

We know,

∠OPT=∠OQT=90

∘

(Angle between the tangent and the radial line at the point of intersection of the tangent at the circle)

Now, in quadrilateral POQT

Sum of angles=360

∠OPT+∠OQT+∠PTQ+∠POQ=360

∘

90+90+∠PTQ+110=360

∠PTQ=360−290

∠PTQ=70
