Answer/Step-by-step explanation:
The corresponding side lengths of two triangles are always equal. Apply this in solving for x
4.

Cross multiply

6x = 45
divide both sides by 6
y = 7.5
5.

Cross multiply

8x = 110
divide both sides by 8
x = 13.75
6.

Cross multiply

7x = 48
divide both sides by 7
x = 6.86 (nearest hundredth)
