This is circle based question from Chapter name- circles

Topic – Angle properties of circles

Chapter number- 15

We have that equal circles with centres O and O’ touch each other at X.

OO’ is produced to meet a circle O’ at A.

AC is tangent to the circle whose centre is O. O’D is perpendicular to AC.

Now using these information we have to find the value of :(i) AO′/AO (ii) areaofΔADO′/areaofΔACO
