find the exact perimeter of the triangle?

a=4x b=x and c is missing

To find the perimeter of a triangle, you need to add the lengths of all three sides.

Given that side a = 4x, side b = x, and side c is missing, the perimeter of the triangle can be expressed as:

Perimeter = a + b + c

Since c is missing, we cannot determine the exact perimeter of the triangle without the length of side c.
