Solution
Let's break this down step by step to determine the graph and the quadrant for the angle .
Step 1: Determine the angle's direction
The angle is negative, which means it is measured clockwise starting from the positive x-axis. To understand where this angle lies, we need to find a positive coterminal angle.
Step 2: Find the positive coterminal angle
A coterminal angle is found by adding (which is a full circle) to the given angle. In this case, we'll add to :
So, the positive coterminal angle is .
Step 3: Identify the quadrant
Since is a positive angle less than , it lies in Quadrant I.
However, the original angle is a negative rotation. We can conclude that it wraps clockwise and lands in Quadrant IV, because adding the full circle leads us to a coterminal angle in Quadrant I.
Part 2: The angle is in Quadrant IV.
