Answer:
9 cm
Step-by-step explanation:
Side lengths of similar triangles are proportional. BC is 1.5 times the length of AC, so EF will be 1.5 times the length of DF:
1.5·6 cm = 9 cm
Answer:
21
Step-by-step explanation:
Answer:
Twelve-fifths.
Step-by-step explanation:
The diagram is shown below
Given triangle be right angled at
,
Withe reference to
,
Its opposite side is
, adjacent side is
and hypotenuse is 
We are to find the value of 
We know 
Substituting the above values we get,

So the answer is Twelve-fifths.
The value of x is 8 from the diagram given.
<h3>How do you calculate the sides of similar triangles?</h3>
The corresponding sides of a similar triangle are said to be in proportion if and only if the corresponding angle are also equal.
To calculate the side of line x (|x|), we have to determine the ratios of the corresponding sides as:


x = 120/15
x = 8
Therefore, we can conclude that the value of x is 8.
