Solving for X and Y
![### Find the Values of x and y:
This diagram presents a set of intersecting lines forming various angles, with the task to find the values of angles \( x^\circ \) and \( y^\circ \). The key points and features of the diagram are as follows:
1. **Points and Labels:**
- Points: \( C \), \( D \), \( E \), \( F \), \( G \), and \( H \).
- The lines CD, EF, and FG intersect at point \( H \).
2. **Given Angles:**
- There are two \( x^\circ \) angles adjacent to each other between lines CD and EF.
- There is one \( y^\circ \) angle between lines DE and EF.
- One angle marked \( 71^\circ \) between lines FG and EF.
- One right angle ( \( 90^\circ \)) marked by a small red square between parts of lines near point \( H \).
3. **Identifying Relationships:**
- The sum of angles around a point is \( 360^\circ \).
- Adjacent angles on a straight line sum up to \( 180^\circ \).
- The right angle is \( 90^\circ \).
Using the information on the diagram, let’s determine the values of \( x^\circ \) and \( y^\circ \):
1. **Right Angle (\( 90^\circ \)):**
- The small red square indicates a right angle between a portion of the lines around point \( H \).
2. **Sum of Angles:**
- The angles around point \( H \) must sum up to \( 360^\circ \).
Thus,
\[ 2x + y + 71^\circ + 90^\circ = 360^\circ. \]
3. **Solving for \( x \) and \( y \):**
Rearranging the equation,
\[ 2x + y + 161^\circ = 360^\circ \]
\[ 2x + y = 199^\circ \]
Unfortunately, we cannot solve for \( x \) and \( y \) exactly without an additional equation relating \( x \) and \( y \) specifically. Further context or angles would be required to find an exact numerical value for \( x \) and \( y \).
