Answer:

4.8 inches

Explanation:

See comment for complete question

Represent the larger triangle with 1 and the smaller with 2.

So, we have:


H_1 =6\ in -- height of 1

Required

Determine H2 --- Height of 2

To do this we apply dilation formula.


Original * Scale\ Factor = New

In this case:


H_1 * Scale\ Factor = H_2

Substitute 6 for H1 and 0.8 for Scale Factor


6* 0.8 = H_2


4.8= H_2

Hence, the height of the smaller triangle is 4.8 inches
