To find the measure of the third angle, we can use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is always 180 degrees.

Let's call the measure of the third angle x.

According to the Triangle Angle Sum Theorem, we can set up the following equation:

63° + 40° + x = 180°

Simplifying the equation, we have:

103° + x = 180°

Now, we can solve for x by subtracting 103° from both sides of the equation:

x = 180° - 103°

x = 77°

Therefore, the measure of the third angle is 77°.
