18= 2×3×3 12=2×2×3
1 2 2 1
=1 × 3 =2 × 3
L.C.M= product of greatest power of each prime factor.
2 2
= 2 × 3
=4×9 = 36
hence, time taken by both to meet again
LCM of 18 & 12 =36 minutes
If line c is parallel to line d, the measure of angle 9 should be the same as angle 11 according to the Corresponding angles postulate. I<span>f a transversal (line b in this case) intersects two lines (lines c and d) and the corresponding angles are congruent, then the lines are parallel.
So now since the m</span>∠11 is 120 and m∠11 is congruent to m∠9 then we can solve for x.
m∠9 = 6x
m∠11 = 120
<span>
6x = 120
Divide both sides by 6 to get x.
6x/6 = 120/6
x = 20
The answer is then A. </span>
