Understanding the Problem

When dealing with geometry and trigonometry, equations are often used to find the measure of various line segments and angles. In this case, we are given a problem that involves finding the measure of ${$ m \overline{EHC} $}$, which is a line segment. To solve this problem, we need to understand the properties of line segments and how they relate to each other.

Analyzing the Options

We are given four different equations to choose from, each with a different operation and value. To determine which equation is correct, we need to analyze each option carefully.

Option A: ${$ m \overline{EHC} + 80 + 35 = 180 $}$

This equation involves adding the measure of ${$ m \overline{EHC} $}$ to 80 and 35, and setting the result equal to 180. However, this equation does not make sense in the context of the problem, as the measure of a line segment cannot be added to other values in this way.

Option B: ${$ m \overline{EHC} + 80 + 35 = 360 $}$

This equation also involves adding the measure of ${$ m \overline{EHC} $}$ to 80 and 35, but sets the result equal to 360. While this equation is more plausible than Option A, it still does not make sense in the context of the problem.

Option C: ${$ m \overline{EHG} - 80 - 35 = 360 $}$

This equation involves subtracting 80 and 35 from the measure of ${$ m \overline{EHG} $}$, and setting the result equal to 360. However, this equation is not relevant to the problem, as we are trying to find the measure of ${$ m \overline{EHC} $}$, not ${$ m \overline{EHG} $}$.

Option D: ${$ m \overline{EHC} + 80 + 35 = 360 $}$

This equation involves adding the measure of ${$ m \overline{EHC} $}$ to 80 and 35, and setting the result equal to 360. This equation makes sense in the context of the problem, as it involves adding the measure of a line segment to other values.

Conclusion

Based on our analysis of the options, we can conclude that the correct equation to find the measure of ${$ m \overlineEHC} $}$ is Option D ${$ m \overline{EHC + 80 + 35 = 360 $}$. This equation is the only one that makes sense in the context of the problem, and it involves adding the measure of a line segment to other values.

Properties of Line Segments

To understand why Option D is the correct equation, we need to understand the properties of line segments. A line segment is a set of points that are connected by a straight line. The measure of a line segment is the length of the line segment, which can be measured in units such as inches or centimeters.

Adding Line Segments

When we add line segments, we are essentially combining them to form a new line segment. The measure of the new line segment is the sum of the measures of the original line segments. For example, if we have two line segments with measures of 3 inches and 4 inches, the measure of the new line segment formed by adding them is 7 inches.

Subtracting Line Segments

When we subtract line segments, we are essentially removing one line segment from another. The measure of the resulting line segment is the difference between the measures of the original line segments. For example, if we have two line segments with measures of 5 inches and 2 inches, the measure of the new line segment formed by subtracting the second line segment from the first is 3 inches.

Applying the Properties to the Problem

Now that we understand the properties of line segments, we can apply them to the problem. We are given the equation ${$ m \overline{EHC} + 80 + 35 = 360 $}$, which involves adding the measure of ${$ m \overline{EHC} $}$ to 80 and 35, and setting the result equal to 360. Using the properties of line segments, we can see that this equation makes sense, as it involves adding the measure of a line segment to other values.

Solving the Equation

To solve the equation ${$ m \overline{EHC} + 80 + 35 = 360 $}$, we can start by combining the constants on the left-hand side of the equation. This gives us ${$ m \overline{EHC} + 115 = 360 $}$. Next, we can subtract 115 from both sides of the equation to isolate the measure of ${$ m \overline{EHC} $}$. This gives us ${$ m \overline{EHC} = 245 $}$.

Conclusion

In conclusion, the correct equation to find the measure of ${$ m \overlineEHC} $}$ is Option D ${$ m \overline{EHC + 80 + 35 = 360 $}$. This equation makes sense in the context of the problem, and it involves adding the measure of a line segment to other values. By applying the properties of line segments, we can solve the equation and find the measure of ${$ m \overline{EHC} $}$.

Final Answer

The final answer is: $\boxed{245}$
