Question

6. The lengths of two sides of a triangle are 5 cm and 8 cm. Between what two measures
should the length of the third side fall?​

Answer 1

Step-by-step explanation:

The sum of two sides of triangle is greater than third side

5+8

=13

The difference of two sides of a triangle is smaller than third side

=8-5

=3

The third side will fall between 3 and 13

Answer 2

Answer:

in triangle ABC

AB=8cm

BC=5cm

AC=?

then

AC(square)=AB(square)+BC(square)

AC(square) =64+25

AC(square)=89

AC=√89
