Question

What is the degree measure of the angle passing through this point?

Answer 1

135 degrees.

Explanation:

Tan theta = √/2 /2 / -√/2 /2 = -1

Arctan 1 = 45 degrees.

As the x coordinate is negative and the y coordinate is positive:

Theta will be in the 2nd quadrant.

So its 180 - 45

= 135 degrees.
