Final answer:
The question lacks context or details to solve for x, which seems to be related to geometric properties of tangency, commonly found in problems involving circles and angles.
Step-by-step explanation:
To find the value of x when segments that appear tangent are tangent, we need specific information regarding the geometrical figures involved or an equation that can be used to calculate x. The question does not provide sufficient context or details to determine the correct value of x. Values like 45°, 60°, 30°, and 90° often represent angles in geometric contexts, and the tangent property usually relates to circles where the tangent line touches the circle at exactly one point and is perpendicular to the radius at the point of tangency.
