Question

1. (6x - 7)° (3x - 29)° (8y + 17)° m l

Explanation:

Step1: Use the property of parallel lines (corresponding angles)

Since \(m\parallel l\), then \(6x - 7=3x - 29\) (corresponding angles).

$$

Also, \(6x - 7+8y + 17 = 180\) (same - side interior angles).
Substitute \(x =-\frac{22}{3}\) into \(6x - 7+8y + 17 = 180\).

Answer:

\(x =-\frac{22}{3}\), \(y=\frac{107}{4}\)
