we know that
An isosceles triangle is a triangle with two equal sides and two equal angles
Let
x-------> the length of the equal sides
y-----> the length of the base
-----> equation A
The perimeter of an isosceles triangle is equal to
so
------> equation B
substitute equation A in equation B
Find the value of y
therefore
<u>the answer is</u>
The dimensions of the triangle are
