Question

I’d really appreciate some help :)

Answer 1

Answer/Step-by-step explanation:

The corresponding side lengths of two triangles are always equal. Apply this in solving for x

4.
`(9)/(6) = (x)/(5)`

Cross multiply

`6*x = 5*9`

6x = 45

divide both sides by 6

y = 7.5

5.
`(10)/(8) = (x)/(11)`

Cross multiply

`8*x = 10*11`

8x = 110

divide both sides by 8

x = 13.75

6.
`(12)/(x) = (7)/(4)`

Cross multiply

`x*7 = 12*4`

7x = 48

divide both sides by 7

x = 6.86 (nearest hundredth)
