Question

In figure AB is a chord of the circle and AOC is
its diameter such that <ACB = 50° . If AT is the
tangent to the circle at the point A, then <BAT
is equal to -
[40°, 50°, 60°, 65°)​

Answer 1

Answer:

40

Step-by-step explanation:

< CAT = 90 (tangent theorem)

Join  AB

< CAB = 90

<BAC = (180-(90-50)) =50

<BAT =<CAT - <BAC = 90-50 =40
