Question

the unequal side of an isosceles triangle is 3 cm more than one of its equal side if the perimeter of the triangle is 18 cm find the length of the three sides

Answer 1

Answer:

Step-by-step explanation:

Let the equal side be x

So, the unequal side will be x+3

Now,

x+x+(x+3)=18

3x+3=18

3x=15

x=5

now we got that the equal side is 5cm

x+3=5+3=8

so the sides of the triangle is 5cm,5cm and 8cm

Answer 2

here is your answer mate
equal side = x
unequal side =x+3
x+x+x+3
3x+3=18
3x+3=18
3x=18-3
3x=15
x=15/3
x=5
x=5,x+3=5+3=8
