Answer:

1st one will be less than 14 as the sum of 2 sides of triangle is always bigger than the third one

Step-by-step explanation:

2) ab²= ac²+ bc²

= 5² + 12²

= 25 + 144

ab² = 169

ab= root over 169 = 13

Length of two sides is 6 cm 8 cm. Between which two numbers can length of the 3rd side fall.

ABC is right angled at C. If AC = 5 cm and BC = 12 cm, find AB

Step-by-step explanation:

Sum of two sides is always greater than remaining side,  so if the other side is 'a'.

a + 6 > 8    also  a + 8 > 6

a > 2          also a > - 2

As it says, a is greater than 2,  a > -2 is obvious.

So, at minimum, a is greater than 2.

And,

6 + 8 > a   ⇒ 14 > a , it means, a is less than 14.

Means, a lies between 14 and 2.

2.  Using Pythagoras theorem,

AB^2 = 12^2 + 5^2

     = 144 + 25

     = 169

AB = √169

     = 13
