Question

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.

Answer 1

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
