D 85°

Answer 1

The supplement of an angle is 180° - the angle, and the complement of an angle is 90° - the angle.

Given that the supplement of the angle is 155°, we can find the angle by subtracting from 180°:
180° - 155° = 25°

Now, to find the complement of the angle:
90° - 25° = 65°

Therefore, the measure of the complement of the angle is 65°.

So, the correct answer is:
B 65°65°
