Answer:
Option B. 1 : 3
Step-by-step explanation:
There are two triangles shown in the picture attached ΔABC and ΔCD.
In these triangles sides AB and DE are parallel and BC is transverse line so ∠ABC = ∠EDC (corresponding angles)
Similarly AC is transverse to parallel lines AB and DE, so ∠BAC = ∠DEC (corresponding angles)
∠ACB is common in both the triangles.
Therefore ΔABC and ΔDEC are similar.
We know in similar triangles corresponding sides are in the same ratio.


Therefore ratio of y and 12 is equal to 3 : 1
Or ratio of 12 to y is 1 : 3
Option B is the answer.
1, 3, 5, 7, 9. You could continue on with this pattern forever by adding two to each previous number and it would average out correctly.

Answer:
17
Step-by-step explanation:
1st step is 2c really will be 2 * 4 = 8
2nd step is ab really will be 3*5= 15
3rd step is 3d really will be 3* 2= 6
so your answer will be 17
