11. If m<B = 58 degrees and the sum of m<E and m<D is 122 degrees, what is the measure of <D? So this is a two part question, what equation would you use to solve this problem AND what is the value of <D?

To solve the problem, we first need to set up an equation based on the information given.
1. We know that:
- \( m<B = 58^\circ \)
- The sum of the measures of angles E and D is \( m<E + m<D = 122^\circ \).
2. We can express the measure of angle E in terms of angle D:
\[
m<E = 122^\circ - m<D
\]
3. In this context, we can hypothesize about the relationship between angles B, E, and D. However, without additional information about whether these angles are part of a specific geometric configuration (like a triangle or straight line), we cannot definitively solve for \( m<D \).
Assuming that the angles are part of a triangle with angle B, and assuming angle E and angle D are the other angles, we can use the triangle sum property, which states that the sum of the angles in a triangle is \( 180^\circ \):
\[
m<B + m<E + m<D = 180^\circ
\]
Substituting the known values:
\[
58^\circ + (122^\circ - m<D) + m<D = 180^\circ
\]
4. Simplifying this equation:
\[
58^\circ + 122^\circ = 180^\circ
\]
\[
180^\circ = 180^\circ
\]
This indicates that we need to solve for \( m<D \) using the earlier equation \( m<E + m<D = 122^\circ \).
### Set up the equations:
Assuming:
- Let \( m<D = x \).
- Then \( m<E = 122 - x \).
We do not have a direct relationship without knowing how \( E \) and \( D \) interact with \( B \) and potentially other angles. If we assume that \( D \) and \( E \) could form another angle, or that they are somehow related to \( 58^\circ \):
To actually find the measure of angle \( D \), we need more information about \( E \) or how the angles relate (like whether they are vertical angles, part of a triangle, etc.).
For angles \( E \) and \( D \):
- We can say \( m<D + m<E = 122^\circ \).
But without an additional relationship or value for \( E \), we can't isolate \( m<D \) in numeric terms.
If we had such details, we could conclusively determine the measure for \( D \). In its current form, knowing only the sum and the single angle (B), we cannot directly find just \( m<D \).
### Conclusion:
You can assume different relationships based on geometric principles, but without loss of generality due to missing context, you cannot solve for \( m<D \) explicitly with the current information provided.
Thus, we need:
1. **Equation**: \( m<E + m<D = 122^\circ \) with other relationships to find a concrete value.
2. **Value**: Cannot be determined without further relationships.
Assuming all angles in a triangle (B, E, D):
1. We have \( x + (122 - x) + 58 = 180 \)
2. Therefore: Any value leading hypothetically gives \( m<D = x \) and without loss relates to \( (sum = 58 + E + D = 180)\)
For definitive measure of \( m<D \):
- We need \( E \) to finalize numeric concrete angles.

- \( m<B = 58^\circ \)
