A right triangle always has one angle that measures 90 degrees. Therefore, the sum of the measures of the three angles in a right triangle is always 180 degrees.
To find the third angle, we can subtract the measures of the known angles from 180 degrees.
Third angle = 180 degrees - 90 degrees - 65 degrees
Third angle = 180 degrees - 155 degrees
Third angle = 25 degrees
Therefore, the third angle in the triangle measures 25 degrees.
if a right triangle has an angle at 65 degrees, what is the third angle in the triangle
