    Answer:

    x = 12.5

    Step-by-step explanation:

    The three sides of the triangle have lengths 3x, 3x, and 15.

    The perimeter of the triangle is the sum of the three lengths, and it is 90.

    Perimeter = 3x + 3x + 15 = 6x + 15

    3x + 3x + 15 = 90

    6x + 15 = 90

    6x = 75

    x = 12.5
