Question

The triangles are similar. Find x.
Please help me!

Answer 1

GIVEN -> Triangles r similar

so sides r in ratio

`(2.4)/(3) = (2.8)/(x) \\ 0.8 = (2.8)/(x) \\ x = (2.8)/(0.8) \\ x = (28)/(8) \\ x = 3.5 \: \: ans`

Answer 2

3.5

Explanation:

We can write a ratio to solve

2.4 2.8

----- = --------

3 x

Using cross products

2.4x = 3(2.8)

2.4x =8.4

Divide each side by 2.4

2.4x /2.4 = 8.4/2.4

x = 3.5
