In a right triangle, one of the angles is always 90°, as it is a right angle. Since the sum of the angles in a triangle is always 180°, we can find the third angle by subtracting the given angles from 180°.
The sum of the angles in a triangle is given by:
180° = 90° + 65° + Third angle
Subtracting 90° and 65° from both sides:
180° - 90° - 65° = Third angle
The third angle in the triangle is:
Third angle = 180° - 90° - 65° = 25°
a right triangle has an angle that is 65° , what is the third angle in the triangle?
