Answer:
20 units
Step-by-step explanation:
Since the triangle is equilateral then all 3 sides are equal in length.
Equate any 2 sides and solve for x
4x = 3x + 5 ( subtract 3x from both sides )
x = 5
hence
4x = 4 × 5 = 20
3x + 5 = (3 × 5) + 5 = 15 + 5 = 20
7x - 15 = (7 × 5) - 15 = 35 - 15 = 20
The lengths of the sides are 20 units
