(10.02) the point (−3, 1) is on the terminal side of angle θ, in standard position. what are the values of sine, cosine, and tangent of θ? make sure to show all work.

Part 1)

Part 2)

Part 3)

Step-by-step explanation:

we know that

The angle is in the second quadrant  so the sine is positive, the cosine is negative and the tangent is negative

step 1

Find the radius r applying the Pythagoras theorem

substitute the given values

step 2

substitute values

Simplify

step 3

Find the value of

substitute values

Simplify

step 4

Find the value of
