Final Answer:

The value of x is
\( (15)/(2) \).

Step-by-step explanation:

In the given scenario, we have triangle MNO where MO is extended through point O to point P. Let's denote the angles in the triangle as follows:
\( \angle MNO = (3x + 11)^\circ \), \( \angle OMN = (2x + 20)^\circ \), and
\( \angle NOP = (8x - 5)^\circ \). According to the interior angle sum property of a triangle, the sum of all angles in a triangle is
\( 180^\circ \).

Setting up the equation for the sum of angles in triangle MNO, we get:

(3x + 11) + (2x + 20) + (8x - 5) = 180

Combining like terms, we simplify the equation:


\[ 13x + 26 = 180 \]

Solving for x:


\[ 13x = 154 \]


\[ x = (154)/(13) = (22)/(2) = (15)/(2) \]

Therefore, the value of x is
\( (15)/(2) \). This solution ensures that the sum of interior angles in triangle MNO is
\( 180^\circ \), satisfying the geometric conditions for a triangle.

The solution involves applying basic geometric principles and algebraic manipulation to find the value of x that satisfies the given conditions for the triangle's interior angles. The result
\( (15)/(2) \) ensures the geometric consistency of the triangle.
