Question

Can someone help me

Answer 1

3 cm

Explanation:

First, we have to understand what happens if two shapes are similar. When two shapes are similar, the angles are equal in both. This means the sides will be in the same ratio from one shape to another.

`(7.2)/(t)=(9.6)/(4)`

Using the equation above, we can find t. We use cross multiplication (ad = bc)

7.2 * 4 = 9.6t

9.6t = 28.8

t = 3 cm
