Answer:
Here;
Base of the isosceles triangle = 5/3 cm
We know that;
A isosceles triangle has any two sides equal.
Therefore... The 2nd side will be also 5/3 cm.
Now..
Sum of 1st and 2nd side of triangle = 1.66 + 1.66
= 3.32
According to the ques:
Perimeter = 180cm
So 3rd side=( perimeter - sum of 2 equal sides)
= ( 180-3.32) cm
=149.68 cm
