Answer:
40 degrees
Step-by-step explanation:
The three angles in a triangle add up to 180 degrees. Therefore, if you know the measurements of two angles, you can figure out the measurement of the other angle by doing this:
180 degrees - 65 degrees - 75 degrees = 40 degrees
If you want to check your answer, 65 degrees + 75 degrees + 40 degrees = 180 degrees.
