Answer:
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
