To find the length of the unknown sides of the

Answer to Problem 16E
The length of the other two sides are 8.1 yd each
The triangle is an isosceles triangle.
Explanation of Solution
Given information:
Perimeter of the triangle is 22.5 yd
Length of one side is 6.3 yd
Length of remaining two sides are same
Calculation:
Perimeter of the triangle is 22.5 yd
Length of one side is given as 6.3 yd
Let the length of one side of triangle be x
Since two sides of the triangle are same -
Now add both x together
Subtract 6.3 from both the sides
This gives us
Now, divide both sides by 2
This gives us −
Both the sides of the triangle is 8.1ydeach
Conclusion- The length of the unknown side is 8.1 yd each.
Since, two sides of the triangle are same and one is different it is an isosceles triangle.
