Draw the angle. It should be clear that
y = -5
x = 2
r = √29
Now just recall that
sinθ = y/r
cosθ = x/r
tanθ = y/x
now let 'er rip
The point P(2, -5) is located on the terminal arm of an angle θ in standard position.
a) Draw and label an appropriate diagram. Remember to label θ and all the sides of the triangle.
b) Determine the exact values of the primary trigonometric ratios for angle θ.
c) Determine the measure of angle θ to the nearest degree.
