Elena-2011 [213]
You can set this up as 2 fractions equal to each other, like ratios.

18/11=108/x

Cross multiply and you get 18x=1,188

Now divide both sides by 18 and get x.

x=66.

If the height of the building is 108ft, the width is 66ft.

Which of the following three sets of lengths could be used to form a right triangle A 39,15 and 36
laila [671]

Step-by-step explanation:

To find a set of 3 leg lengths that will form a right-angled triangle, the square of the largest leg must be equal to the sum of the squares of the other 2 legs.

We try out all the options:

39² = 1521, 15² + 36² = 1521.

12² = 144, 8² + 4² = 80.

17² = 289, 13² + 9² = 250.

Since 39² equals 15² + 36², option A is the correct answer.
