The sine of angle A in the right triangle shown is 12/13.
What is the sine of an angle?
The sine of an angle is the ratio of the opposite side of that angle to the hypotenuse.
In the given right angle triangle,
Perpendicular = 12
Base = 5
Hypotenuse = 13
So, the value of Sin A = Perpendicular/Hypotenuse = 12/13.
Therefore, the sine of angle A in the right triangle shown is 12/13.
