Find the value of x.
A. 45
B. 40
C. 22.5
D. 95

To find the value of \( x \), we need to use the properties of the angles involving the circle and the tangents.

Given:
- The angle between the tangent and the chord through the point of contact is equal to the angle in the alternate segment. 
- The angle \( (4x + 5)^\circ \) is an exterior angle for the triangle formed, which is equal to the sum of the non-adjacent interior angles.

Since the angle at \( O \) (the center of the circle) subtended by the arc is \( 4x + 5 \), the angle formed at the tangent \( 50^\circ \) is equal to this angle due to the alternate segment theorem.

Thus, we have the relationship:
\[ 50^\circ + x = 4x + 5 \]

Rearranging this equation to solve for \( x \):
\[ 50 + x = 4x + 5 \]
\[ 50 + x - 4x = 5 \]
\[ 50 - 3x = 5 \]
\[ 50 - 5 = 3x \]
\[ 45 = 3x \]
\[ x = \frac{45}{3} \]
\[ x = 15 \]

So, the value of \( x \) is not among the provided options (45, 40, 22.5, 95). Therefore, let's recheck the question for any mistake or further analysis if needed.
