Find the measure of the unknown angle.61°164°?

The sum of angles in a triangle is 180 degrees. If you have two angles, 61° and 164°, you can find the third angle by subtracting the sum of the two given angles from 180.

Step 1: Add the two given angles. 61° + 164° = 225°

Step 2: Subtract the sum from 180. 180° - 225° = -45°

However, an angle cannot be negative. This means that the given angles do not form a triangle. There seems to be a mistake in the problem as the sum of the two given angles is already more than 180°. Please check the problem again.
