Answer:
the Ratio between the small and big triangles is that of b. 
Step-by-step explanation:
We can solve this ratio problem by using the <u>Rate of Change formula</u> as shown below,

In this situation y would be the smaller triangle and x would be the larger triangle. Since all the values are given to use we can just plug those values in and solve for the rate of change / ratio.

So the rate of change or ratio between the small and big triangles is that of
