Answer:
9.33 feet = 111.96 inches
Step-by-step explanation:
If we have similar triangles, the rate between matching sides is the same.
So the length of the smaller ladder (18 ft) over the length of the taller ladder (24 ft) is equal to the distance from the bottom of the smaller ladder to the tree (7 ft) over the distance from the bottom of the taller ladder to the tree (x ft):
18 / 7 = 24 / x
x = 7 * 24 / 18
x = 9.33 feet
To find this measure in inches, we just need to multiply by 12:
x = 9.33 * 12 = 111.96 inches
Answer:
w = 3.2 m
Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
= 
, that is
= 
( cross- multiply )
8.5w = 27.2 ( divide both sides by 8.5 )
w = 3.2 m

Step-by-step explanation:
Answer:
9, 10, 3 and 1/3
Step-by-step explanation:
21 = 7 x 3
Therefore divide each side of the larger triangle by three to get the smaller one.
27/3 = 9
30/3 = 10
10/3 = 3.33333...
