Answer:

12

Step-by-step explanation:

When looking at triangles it's always important to remember what the ratios are to parts of triangles. In the case of this triangle let's give the value 24 the variable of E. In every scenario in which Y is positioned above 24 or E, the answer is always E/2=y, or 24/2=y ---> 12.

y / 24 = 12 / 12 + 18

y / 24 = 12 / 30

y / 24 = 2 × 6 / 5 × 6

y / 24 = 2 / 5

y = 24 × 2 / 5

y = 48 / 5

y = 96 / 10

y = 9.6
