# Finding Unknown Angle Measures Supplementary Angles 5 Answer Key

Supplementary angles are two angles whose sum is 180 degrees. When solving for unknown angle measures, it is important to remember this rule. This article will provide an answer key and explain the process of finding unknown angle measures for supplementary angles 5.

## Steps for Finding Unknown Angle Measures for Supplementary Angles 5 The first step in finding unknown angle measures for supplementary angles 5 is to identify the known angle in the problem. For this problem, the known angle is given as 5 degrees. The next step is to subtract the known angle from 180 degrees to get the unknown angle measure. In this case, the unknown angle measure is 175 degrees.

## Uses of Supplementary Angles Supplementary angles are used to calculate the measure of angles when the measure of one angle is known. It is also used to solve for the measure of angles when the sum of two angles is known. Supplementary angles are also used in geometry to solve for the measure of angles in different shapes such as triangles, rectangles, and parallelograms.

## Tips for Solving Problems with Supplementary Angles When solving problems with supplementary angles, it is important to remember that the sum of two supplementary angles is always 180 degrees. It is also important to remember that when one angle is given, the other angle can be found by subtracting the measure of the given angle from 180 degrees. Additionally, it is important to understand the concept of supplementary angles and how they can be used to solve different types of problems.

## Conclusion Finding unknown angle measures for supplementary angles 5 can be done by subtracting the known angle measure from 180 degrees. Supplementary angles are used to calculate the measure of angles when the measure of one angle is known or when the sum of two angles is known. It is important to remember that the sum of two supplementary angles is always 180 degrees and that one angle can be found by subtracting the measure of the given angle from 180 degrees. With this information, it is easy to find unknown angle measures for supplementary angles 5.
