Answer:
Step-by-step explanation:
Given the point (8, -15) is on the terminal side of an angle .
To find the value of .
As the point (8, -15) lies in the fourth quadrant where
In a right angle triangle;
here, adjacent side = x = 8 units and Opposite side = y = -15 units
Using Pythagoras theorem;
Substitute the given values we have;
Sine ratio is defined as in the right angle triangle, the ratio of opposite side to Hypotenuse side.
then;
therefore, the value of is .
