this is your answer

it was very simple just use formula and try to understand the language of the questions

Answer 2

Answer:

Lets find it

Step-by-step explanation:

Let the first side=x

Then, the second side=x+2

Then, the third side=2x-3

ATQ;

x+x+2+2x-3=19cm

4x-1=19 cm

4x=19+1 = 4x=20 = x=20/4=5

The first side=x=5

The second side=x+2=7

The third side=2x-3=7

Hence, this is an isoceles triangle
