Final answer:
The measure of the third angle in a triangle can be found by subtracting the sum of the given angles from 180 degrees. In this case, the third angle measures 80 degrees.
Step-by-step explanation:
The sum of the angles in a triangle is always 180 degrees. To find the measure of the third angle, we need to subtract the sum of the given angles from 180 degrees.
Given angle 1 = 35 degrees and angle 2 = 65 degrees:
Third angle = 180 degrees - 35 degrees - 65 degrees
Third angle = 80 degrees
