The Triangle Angle Sum Theorem states that the sum of the three angles in a triangle is always 180 degrees.
In the triangle with angles 45°, 45°, and 90°, the sum is 45° + 45° + 90° = 180°. Therefore, the measures of each angle are 45°, 45°, and 90°.
In the triangle with angles 27.5°, 62.5°, and 90°, the sum is 27.5° + 62.5° + 90° = 180°. Therefore, the measures of each angle are 27.5°, 62.5°, and 90°.
In the triangle with angles 32.2°, 57.8°, and 90°, the sum is 32.2° + 57.8° + 90° = 180°. Therefore, the measures of each angle are 32.2°, 57.8°, and 90°.
In the triangle with angles 40°, 50°, and 90°, the sum is 40° + 50° + 90° = 180°. Therefore, the measures of each angle are 40°, 50°, and 90°.
Therefore, the correct answer is:
40°, 50°, 90°.
