To determine the values of \( m \) and \( n \) that ensure quadrilateral ABCD is a parallelogram, we need to use the properties of angles in a parallelogram.
In a parallelogram:
1. Opposite angles are equal.
2. Consecutive angles are supplementary (they add up to \( 180^\circ \)).
Given the angles in quadrilateral ABCD as:
- \( \angle A = m \)
- \( \angle B = n \)
- \( \angle C = m + 20^\circ \) (for example)
- \( \angle D = n - 10^\circ \) (for example)
To ensure ABCD is a parallelogram, we can use these properties.
If \( \angle A \) and \( \angle C \) are opposite angles:
\[
m + 20^\circ = m
\]
This equation doesn’t make sense unless \( 20^\circ = 0^\circ \). Thus, we need to consider consecutive angles.
If \( \angle A \) and \( \angle B \) are consecutive angles, we have:
\[
m + n = 180^\circ
\]
If \( \angle C \) and \( \angle D \) are consecutive angles, we find:
\[
(m + 20^\circ) + (n - 10^\circ) = 180^\circ
\]
This simplifies to:
\[
m + n + 10^\circ = 180^\circ
\]
So:
\[
m + n = 170^\circ
\]
So, the key conditions we can use to ensure that quadrilateral ABCD is a parallelogram are:
- If \( m + n = 180^\circ \) or if \( m + n = 170^\circ \).
Therefore, for specific values:
1. \( m = 70^\circ \), \( n = 110^\circ \) would satisfy the first equation (\( m + n = 180^\circ \)).
2. \( m = 80^\circ \), \( n = 90^\circ \) would satisfy the second (\( m + n = 170^\circ \)).
Please provide the specific angle measures originally given in the image for more specific answers. Otherwise, you can choose values of \( m \) and \( n \) based on these conditions.

To determine the values of \( m \) and \( n \) that ensure quadrilateral ABCD is a parallelogram, we can utilize the properties of the angles given. According to the properties of a parallelogram:
1. Opposite angles are equal.
2. Consecutive angles are supplementary (their sum equals \( 180^\circ \)).
Given:
- \( \angle A = 3n + 3 \)
- \( \angle B = 5m \)
- \( \angle C = 3m + 30 \)
- \( \angle D = 105^\circ \)
Since \( \angle A \) and \( \angle C \) are opposite angles, we can set them equal to each other:
1. \( \angle A = \angle C \)
\[
3n + 3 = 3m + 30
\]
2. For consecutive angles, we can set up the equation for \( \angle B \) and \( \angle A \):
\[
\angle A + \angle B = 180^\circ
\]
\[
(3n + 3) + 5m = 180
\]
3. Similarly, use angle \( D \) and angle \( C \):
\[
\angle C + \angle D = 180^\circ
\]
\[
(3m + 30) + 105 = 180
\]
Now, let's solve these equations one by one.
### Step 1: Solve \( 3n + 3 = 3m + 30 \)
Rearranging gives us:
\[
3n - 3m = 27 \quad \text{(Equation 1)}
\]
### Step 2: Solve \( (3n + 3) + 5m = 180 \)
Rearranging gives us:
\[
3n + 5m = 177 \quad \text{(Equation 2)}
\]
### Step 3: Solve \( (3m + 30) + 105 = 180 \)
Rearranging gives us:
\[
3m + 135 = 180
\]
\[
3m = 45
\]
\[
m = 15 \quad \text{(Found \( m \))}
\]
### Step 4: Substitute \( m = 15 \) into Equation 1
Substituting into Equation 1:
\[
3n - 3(15) = 27
\]
\[
3n - 45 = 27
\]
\[
3n = 72
\]
\[
n = 24 \quad \text{(Found \( n \))}
\]
### Conclusion
Thus, the values of \( m \) and \( n \) that guarantee that quadrilateral ABCD is a parallelogram are:
- \( m = 15 \)
- \( n = 24 \)
1. Opposite angles are equal.
2. Consecutive angles are supplementary (their sum equals \( 180^\circ \)).
Given:
- \( \angle A = 3n + 3 \)
- \( \angle B = 5m \)
- \( \angle C = 3m + 30 \)
- \( \angle D = 105^\circ \)
Since \( \angle A \) and \( \angle C \) are opposite angles, we can set them equal to each other:
1. \( \angle A = \angle C \)
\[
3n + 3 = 3m + 30
\]
2. For consecutive angles, we can set up the equation for \( \angle B \) and \( \angle A \):
\[
\angle A + \angle B = 180^\circ
\]
\[
(3n + 3) + 5m = 180
\]
3. Similarly, use angle \( D \) and angle \( C \):
\[
\angle C + \angle D = 180^\circ
\]
\[
(3m + 30) + 105 = 180
\]
Now, let's solve these equations one by one.
### Step 1: Solve \( 3n + 3 = 3m + 30 \)
Rearranging gives us:
\[
3n - 3m = 27 \quad \text{(Equation 1)}
\]
### Step 2: Solve \( (3n + 3) + 5m = 180 \)
Rearranging gives us:
\[
3n + 5m = 177 \quad \text{(Equation 2)}
\]
### Step 3: Solve \( (3m + 30) + 105 = 180 \)
Rearranging gives us:
\[
3m + 135 = 180
\]
\[
3m = 45
\]
\[
m = 15 \quad \text{(Found \( m \))}
\]
### Step 4: Substitute \( m = 15 \) into Equation 1
Substituting into Equation 1:
\[
3n - 3(15) = 27
\]
\[
3n - 45 = 27
\]
\[
3n = 72
\]
\[
n = 24 \quad \text{(Found \( n \))}
\]
### Conclusion
Thus, the values of \( m \) and \( n \) that guarantee that quadrilateral ABCD is a parallelogram are:
- \( m = 15 \)
- \( n = 24 \)

\[
(3n + 3) + 5m = 180
\]
This simplifies to:
\[
3n + 5m = 177 \tag{2}
\]
### Step 3: Use the second consecutive angle property

3n - 45 = 27
\]
\[
3n = 72

(Correct: \( A = C \))
2. **Check consecutive angles:**

B = 5(15) = 75
\]
\[
D = 105
\]
\( B + D = 75 + 105 = 180 \) (Correct: \( A + B = 180 \))
