Final answer:
The sum of the measures of the angles in a triangle is always 180 degrees. To find the measure of the missing angle, subtract the sum of the given angles from 180 degrees.
Step-by-step explanation:
In a triangle, the sum of the measures of the angles is always 180 degrees. So, to find the measure of the missing angle, you would subtract the sum of the given angles from 180 degrees.
For example, if you are given two angles of a triangle, let's say 45 degrees and 60 degrees, you would add these two angles together to get 105 degrees. Then, you would subtract 105 degrees from 180 degrees to find the measure of the missing angle, which would be 75 degrees.
