The value of x in the intersecting lines is 24.
The value of angle 6 is 79 degrees.
How to find angles in intersecting lines?
When parallel lines are cut by a transversal line, angle relationships are formed such as corresponding angles, alternate angles, linear angles, vertically opposite angles etc.
Therefore,
∠6 = 3x + 7(corresponding angles)
Corresponding angles are congruent.
Therefore,
3x + 7 + 4x + 5 = 180(sum of angles on a straight line)
7x + 12 = 180
7x = 168
x = 168 / 7
x = 24
∠6 = 3x + 7 = 3(24) + 7 = 72 + 7 = 79 degrees.
