Question

The sides of a triangle are 9,11,13.The largest side of a triangle like this is 39.The other two sides of the second triangle are?
A) 18;22 B)27;33 C)3;11 3 D)48;50

Answer 1

Length of other two sides is 27:33

Option B

Step-by-step explanation:

Here we have , The sides of a triangle are in ratio 9:11:13.The largest side of a triangle like this is 39. Let's calculate other two sides of the second triangle:

$9:11:13$ is the ratio  ,largest ratio value is 13 which represents largest side ratio whose length is 39 :

⇒ $13x = 39$

⇒ $x = \frac{39}{13}$

⇒ $x = 3$

Now, other two sides are 9 x and 11 x

i.e. $9x = 9(3) = 27$

 $11x = 11(3) = 33$

So, lengths of all the three sides are 27:33:39 . And, Length of other two sides is 27:33`
