It is really helpful.
After reading you will get the answer, but since u asked, the angle drawn by then tangent with the chord as given in the original circle is half the angle of the intercepted arc. Here AC is the minor arc. So, angle made by the tangent is (75+36)/2.
If you guys can pls post the OA, it will be really helpful for all of us.
Hope it helps everyone..
Keep rocking guys!!!!!
4days to go to GMAT again!!!!!
