## How do you find the reference angle of 290 degrees?

Reference angle for 290°: 70° Reference angle for 295°: 65° Reference angle for 300°: 60° (π / 3)

## What is the reference angle for 330 degrees?

Since 330 is thirty less than 360, and since 360° = 0°, then the angle 330° is thirty degrees below (ie, just before) the positive x-axis in the fourth quadrant. So its reference angle is 30°.

## What is the reference angle of 240?

The reference angle of 240° is 60°.

## What is the reference angle of 150 degrees?

If you look at a graph, there is a 150° angle in quadrant II, so the reference angle is θ’ = 180° – 150° = 30°.

## What is the reference angle of 180?

If the end face is in the second quadrant (angle from 90° to 180°), our reference angle is 180° minus our given angle. So if our given angle is 110°, then its reference angle is 180° – 110° = 70°.
