Answer:
5.1 units
Step-by-step explanation:
At first we should know that, the sum of the lengths of any two sides of a triangle is greater than the length of the remaining side.
Given: An isosceles triangle has a base 10 units long.
Let the length of each side of the congruent sides = x
So, x + x > 10
2x > 10
x > 5
the congruent side lengths have measures to the first decimal place,
So, the congruent side lengths have measures to the nearest tenths.
So, the shortest possible length of the sides = 5.1 units
