6/42 in simplest form :
Divide both the nominator and the denominator by the HCF (highest common factor) : 6
6/42 = 6:6/42:6 = 1/7
3x : 2 = 15
3x = 15 * 2
3x = 30
x = 30 : 3
x = 10
--------------------------------
3(10) :2 = 15
The second choice is correct
∠KLN and ∠MLI make up a pair of vertical angles.
Vertical angles share a vertex and are the opposite angles formed by intersecting lines. They are also congruent, but just because two angles are congruent doesn't mean they are vertical. That's why ∠KLN and ∠JIG are NOT vertical, for instance.
Answer:
(180-x)⁰ or it might also be X⁰
