If both triangles are similar the ratio of sides will be same

Answer:
x=2
Step-by-step explanation:
2x+4=8
2x=8-4
2x=4
x=4/2
x=2
Here, we need to set up a proportion.
4.5 miles in 15 minutes.
In 75 minutes, how much miles can he ride?
4.5/15 = x/75
Cross multiply
4.5 * 75 = 337.5
15*x = 15x
15x = 337.5
15x/15 = 337.5/15
x= 22.5
Final answer:- Tommy can ride 22.5 miles in 75 minutes.
