**Find the Angle Measure CPALMS.org**

If two angles are complementary, that means that they add up to 90 degrees. This is very useful knowledge if you have a figure with complementary angles and you know the measurement of one of those angles. In this tutorial, see how to use what you know about complementary angles to find a missing angle measurement!... Add the measurements of the two small angles to find the measurement of the large angle for each problem.

## How To Find Unknown Anglea

### First identify the two lines that are parallel. Call these the top and bottom lines. Mark the two corners on the left A and B. Then angle A + angle B = 180 degrees.

- A more accurate angle measure would have been 22.61986495°. If you use that value instead of 23°, you will get answers that are more consistent.. If you use that value instead of 23°, you will get answers that are more consistent..
