Question

Answer 1

Hi THERE!!!

Given :- 1st side of a triangle = 8.2 cm

2nd side of a triangle = 7.8 cm

Let 3rd side be x.

Perimeter of Triangle = sum of all sides

23cm = 8.2 + 7.8 + x

23 = 16 + x

23 - 16 = x

7 = x

So , the third side of a triangle = 7 cm

THANKS❤❤

Answer 2

8.2+7.8+X=23
16+X=23
X=23-16
X=7
