Please Answer This Two Questions

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
