if a right triangle has an angle that is 65, what is the third angle in the triangle?
The sum of angles in a triangle is always 180 degrees.
If one angle in a right triangle is 90 degrees, and another angle is 65 degrees, we can find the measure of the third angle by subtracting the sum of the other two angles from 180.
Third angle = 180 - 90 - 65
Third angle = 180 - 155
Third angle = 25 degrees
