Understanding Complementary Angles
Complementary angles are two angles whose measures add up to 90 degrees. If we denote the angle we are looking for as "x," then its complementary angle can be expressed as "90 - x."
Setting Up the Equation
According to the problem, the angle "x" is double its complementary angle. Therefore, we can set up the equation as follows:
- x = 2(90 - x)
Solving the Equation
Now, let's solve this equation step by step:
- Distribute the 2:
x = 180 - 2x
- Move the term involving x to one side of the equation:
x + 2x = 180
3x = 180
- Divide both sides by 3:
x = 60
Conclusion
The measure of the angle which is double of its complementary angle is 60 degrees.
Verification
To ensure the solution is correct, we can check:
- The complementary angle of 60 degrees is:
90 - 60 = 30 degrees
- Is 60 degrees double of 30 degrees?
Yes, 60 = 2 * 30.
Therefore, the answer is confirmed, and the correct option is A) 60°.
