Question

Value of 's 'if three sides of the triangles are 10 cm,15cm,5cm​

Answer 1

Answer:

The sum of the lengths of any two sides of a triangle is greater than the length of the third side.

Here, 5 + 15=  20 > 10

10 + 15 = 25 > 5

But, 10 + 5 = 15 !> 15 (15 == 15)

Which fails the traingle property. Hence it is not posible to make a traingle with these sides.

Answer 2

Answer:

Well idk what 's' u r asking for but till I know in mathematics 's' represent semi-perimeter So,

solution,

let,

a=10cm

b=15cm

c=5cm

Now,

Semi-perimeter = (a+b+c)/2

=(10+15+5)/2

=30/2

=15 cm
