Step-by-step Solution
To find the value of \( x \), we need to use the information given about the angles \( \angle EHG \) and \( \angle FHG \).
We know that:
- \( m \angle EHG = 68^\circ \)
- \( m \angle FHG = 9x - 2 \)
If \( EHG \) and \( FHG \) are angles that are supplementary (which is a common scenario in geometry), then we can set up the equation:
\[
m \angle EHG + m \angle FHG = 180^\circ
\]
Substituting the values we have:
\[
68^\circ + (9x - 2) = 180^\circ
\]
Now, simplify the equation:
\[
68 + 9x - 2 = 180
\]
Combine like terms:
\[
66 + 9x = 180
\]
Next, isolate \( 9x \) by subtracting 66 from both sides:
\[
9x = 180 - 66
\]
\[
9x = 114
\]
Now, divide both sides by 9 to solve for \( x \):
\[
x = \frac{114}{9}
\]
Simplifying \( \frac{114}{9} \):
\[
x = 12.6667 \quad \text{or} \quad x = \frac{38}{3}
\]
Thus, the value of \( x \) is:
\[
\boxed{\frac{38}{3}} \quad \text{or approximately } 12.67
\]
Quick Answer
The value of \( x \) is \( \frac{38}{3} \) or approximately 12.67.
