Answer:

x = (74-28)/2

Step-by-step explanation:

We find the perimeter of a triangle by adding the sides together

s1 +s2+s3 = P

The perimeter is 74

s1 +s2+s3 = 74

We know one of the sides is 28

28 +s2+s3 = 74

The other two sides are equal in length, call them x

28 +x+x = 74

Combine like terms

28+2x = 74

We want to solve for x

Subtract 28 from each side

28-28+2x = 74-28

2x = 74-28

Divide each side by 2

2x/2 = (74-28)/2

x = (74-28)/2
