Find the value of X and Y in the parallelogram
![### Directions:
Find the value of X and Y in the parallelogram below. Show your calculations and equations.
#### Diagram:
- The shape in the diagram is a parallelogram.
- There are four angles, and two of them are labeled with expressions:
- \( (4x - 37)^\circ \)
- \( 49^\circ \)
- \( 4x - 3 \)
- \( \frac{y}{5} \)
#### Solution:
1. **Understanding the properties of a parallelogram:**
- Opposite angles in a parallelogram are equal.
- Adjacent angles in a parallelogram are supplementary (sum to \(180^\circ\)).
2. **Step-by-step calculations:**
**Finding X:**
- Consider the angles \( 4x - 3 \) and \( (4x - 37)^\circ \).
- They must be equal because they are opposite angles in a parallelogram.
\[
4x - 3 = (4x - 37)
\]
- Solving for \( x \):
\[
4x - 3 = 4x - 37
\]
\[
-3 = -37
\]
This indicates an error, as both angles \( 4x - 3 \) and \( 4x - 37 \) contradict the property of equal opposite angles.
**Alternative Approach:**
- Consider the angle \( (4x - 37)^\circ \) and adjacent angle \( 49^\circ \).
- These two angles must add up to \( 180^\circ \) (supplementary angles).
\[
(4x - 37)^\circ + 49^\circ = 180^\circ
\]
\[
4x - 37 + 49 = 180
\]
\[
4x + 12 = 180
\]
\[
4x = 168
\]
\[
x = 42
\]
3. **Finding Y:**
- The angle opposite \( 49^\circ \) is \( \frac{y}{5} \).
\[
\frac{y}{5} = 49](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F9515abb1-920e-411d-9b5f-f7bc9d9dbe1f%2F8385f420-30b9-414e-9129-a714caf74286%2Fu2or7oe_processed.jpeg&w=3840&q=75)
