Understanding Complementary Angles

In the context of geometry, complementary angles add up to 90 degrees. So, if one angle measures 40 degrees, the measure of the other angle can be found using the equation:

[40^\circ + x = 90^\circ]

Where (x) represents the measure of the other angle. Solving for (x), we get:

[x = 90^\circ - 40^\circ] [x = 50^\circ]

Therefore, the measure of the other angle, when two angles are complementary and one measures 40 degrees, is 50 degrees.
