Understanding Supplementary Angles

In mathematics, supplementary angles are two angles whose measures add up to 180 degrees. This concept is crucial in geometry and trigonometry, as it helps us understand the relationships between different angles and shapes. In this article, we will explore the concept of supplementary angles and find the angle that is supplementary to <16.

What are Supplementary Angles?

Supplementary angles are two angles whose measures add up to 180 degrees. For example, if we have two angles, ∠A and ∠B, and their measures are 120 degrees and 60 degrees, respectively, then they are supplementary angles because their sum is 180 degrees (120 + 60 = 180).

Finding the Supplementary Angle to <16

To find the supplementary angle to <16, we need to add 16 to 180 and find the resulting angle. Let's do the math:

180 - 16 = 164

So, the angle that is supplementary to <16 is 164 degrees.

Real-World Applications of Supplementary Angles

Supplementary angles have many real-world applications in various fields, including architecture, engineering, and physics. For example, in architecture, supplementary angles are used to design buildings and structures that are stable and secure. In engineering, supplementary angles are used to design machines and mechanisms that are efficient and effective. In physics, supplementary angles are used to describe the relationships between different physical quantities, such as force and motion.

Examples of Supplementary Angles

Here are a few examples of supplementary angles:

120 degrees and 60 degrees
90 degrees and 90 degrees
135 degrees and 45 degrees
150 degrees and 30 degrees

Tips for Finding Supplementary Angles

Here are a few tips for finding supplementary angles:

Add the two angles together to find their sum.
Set up an equation using the formula: ∠A + ∠B = 180.
Use a calculator or a protractor to measure the angles.

Conclusion

In conclusion, supplementary angles are two angles whose measures add up to 180 degrees. To find the supplementary angle to <16, we need to add 16 to 180 and find the resulting angle. The angle that is supplementary to <16 is 164 degrees. Supplementary angles have many real-world applications in various fields, including architecture, engineering, and physics. By understanding supplementary angles, we can design and build structures that are stable and secure, and describe the relationships between different physical quantities.
