Answer:
We do not have actual triangles as the longest leg of the smaller triangle is greater than the sum of the other two legs. 12 + 24 < 56.
The sum of the two shorter legs of a triangle must always be greater than the longest leg for the triangle to exist.
Step-by-step explanation:
If they were actual triangle dimension, we could use ratios to solve
12/18 = 24/36 = 56/h or h = 84
