the answer is 4.5 ft
Step-by-step explanation:
Step-by-step explanation:
Given that the two fugures in the question above are similar, it means they have the same shape, even though they are if different sizes, the ratio of their corresponding sides are proportional. Thus,
18/x = 8/2
Let's solve for x as required.
We have,
18/x = 8/2
=>Cross multiply:
18 × 2 = 8 × x
36 = 8x
=>Divide both sides by 8
36/8 = x
4.5 = x
x = 4.5 ft

Answer:
7x.
Step-by-step explanation:
2 + 33 = 7x
35 = 7x
Solution is x = 5.
You didn't share any options to choose that's why you didn't get the answer. Anyway, I think I know what you mean and if you have the same in your option list - that will be definitely helpful for you.
