Question

in given figure if TP and tq are two tangents to a circle with Centre O so that angle poq equal to 140 degree then find angle ptq

Answer 1

there is no fig.
but I think the ans.is 70degree...as the angle subtends at the centre of a circle is double the angle subtends by 2 tangents at a particular point.

Answer 2

Answer:

Step-by-step explanation:

<POQ=110°

<OPT=<TQO=90°(the tangent at any point of a circle is perpendicular to the radius through the point of contact)

<POQ+<OQT+<OPT+<PTQ=360°(sum of interior angles are 360°

110°+90°+90°+<PTQ=360°

290°+<PTQ=360°

360°-290°=<PTQ

70°=<PTQ
