To solve for \( x \) in the given problem, we can set up the equation based on the information about the angles.
The two angles are:
- \( 3x \)
- \( 2x + 10 \)
According to the problem, the sum of these two angles is 160 degrees. Therefore, we can write the equation:
\[ 3x + (2x + 10) = 160 \]
Now, let's simplify and solve for \( x \):
\[ 3x + 2x + 10 = 160 \]
Combine the like terms:
\[ 5x + 10 = 160 \]
Next, subtract 10 from both sides:
\[ 5x = 150 \]
Now, divide both sides by 5:
\[ x = 30 \]
Thus, the value of \( x \) is \( \boxed{30} \).
