The base is 11 inches long

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal interior angles

Let

y -----> is the length of the base of the isosceles triangle

x ----> is the length of each of the congruent sides

The perimeter of the triangle is equal to

P=y+x+x

P=y+2x

we have

$P=55\ in$

55=y+2x ----> equation A

$y=\frac{x}{2}$ ----> equation B

solve the system by substitution

substitute equation B in equation A

$55=\frac{x}{2}+2x$

solve for x

$55=\frac{5}{2}x$

$x=55(2)/5\\x=22\ in$

Find the value of y

$y=\frac{x}{2}$ ----> $y=\frac{22}{2}=11\ in$

therefore

The base is 11 inches long
