Answer:
a. sin θ = -8/17.
b. tan θ = -8/15.
c. cos θ = 15/17.
Step-by-step explanation:
Consider the triangle formed by joining the origin to the point and the perpendicular from the point to the x-axis. The triangle will be in the 4th quadrant.
The hypotenuse = √ (15/17^2 + (-8/17)^2 )
= √ 1 = 1.
sin θ = -8/17 / 1
= -8/17
tan θ = -8/17 / 15/17
= -8/15.
cos θ = 15/17 / 1
= 15/17.
