Final answer:
The question about finding the value of x given parallel lines m and n, and angles (7x-30) and (6x-10), cannot be answered without additional information about the position of the angles in relation to the parallel lines.
Step-by-step explanation:
The question provided seems like it's incomplete, but it appears to be about finding the value of x when two angles are given and it is known that lines m and n are parallel. Typically, if angles are formed by a transversal crossing two parallel lines, they might form corresponding angles, alternate interior angles or same-side interior angles which are equal or supplementary depending on the angle type. However, without more information about the position of the angles (7x-30) and (6x-10), we cannot definitively solve for x. We would need additional context such as whether these are corresponding angles, which would be equal, or same-side interior angles, which would sum to 180 degrees. As such, the solution provided in the reference does not match the information given in the question, and further clarification is needed to give a precise answer.
