Answer: 25 degrees
Explanation:
so, that little red square at the top of the triangle means that it is a 90 degree angle. so, we can subtract that since we know the measure of the angle. that gives us 90 degrees left to work with. but, it shows us that one of the angles is 65. so, we can subtract that too since we know the measurement of that as well. that leaves us with 25 degrees. there is only one angle left, so that is the answer.
