Question

. In figure, AB is a chord of the circle with diameter AOC such that
ZACB=50°. If AT is the tangent at A, find Angle BAT​

Answer 1

Answer:

we know that angle subtended by the arc in the remaining will be 1/2 of that subtended in the center

thus angle ABC =90

ABC+BCA+BAC=180(angle sum property )

thus

BAC=40

BAT + BAC = 90(complementary angles)

BAT =90-40

angle BAT= 50
