Question

9. In the given figure, AB is a chord of the circle and AOC is its diameter
such that ACB = 55°. If AT is the tangent to the circle at point A,
then find BAT.
​

Answer 1

Answer:

BAT =45°

Step-by-step explanation:

here OA is perpendicular to AT (radius perpendicular to tangent)

so angle OAT=90°

here angle A is divided into two

I. e., angle OAB and angle BAT

OAT = 90°

if it is divided into two then each angle become 45°

so angle BAT =45°
