Answer:

Step-by-step explanation:

There are two ways to find the value of m∠ ABT

By using trigonometric ratio:

1 - Draw a perpendicular AT

2 - Now the Δ ABT is a right-angle triangle. therefore by using trigonometric ratio

Sine X = Perpendicular / Hypotenuse

Sine X = AT/AB

X = Sine-1 AT/AB.

others ratio can also be used i.e cos x & tan x.

By using Circle Properties

1 - find the radius then the chord AB
