Question

can someone answer all these please​

Answer 1

Step-by-step explanation:

2. Let the base of an isosceles triangle =x

The other two sides are equal and 3cm less than base=x-3,x-3

perimeter of triangle=24cm

Perimeter of triangle=>sum of all sides=24

=>x+x-3+x-3=24

=>3x-6=24

=>3x=30

=>x=10cm

Base of triangle=10cm

the other two equal sides are x-3

=10-3=7cm

Therefore the three sides are 10cm,7cm,7cm
