Final answer:
The complementary angle to 51 degrees is 39 degrees. You find this by subtracting the angle from 90 degrees.
Step-by-step explanation:
In mathematics, complementary angles are pairs of angles that add up to 90 degrees. Thus, to find the measure of the complementary angle of 51 degrees, you need to subtract 51 degrees from 90 degrees. This can be shown by the formula: Complement = 90 - angle.
Applying this formula we get:
- Subtract 51 from 90: 90 - 51 = 39 degrees
Thus, the complementary angle to 51 degrees is 39 degrees.
