Perimeter of triangle:
If the perimeter of the triangle is 90, what is the value of x?

The value of x is 12.5

A triangle has 3 sides: side A, side B and side C

Perimeter of a triangle = side A + side B + side C

Side A = 3x

Side B = 3x

Side C = 15

Perimeter of a triangle = 90

Perimeter of a triangle = side A + side B + side C

90 = 3x + 3x + 15

90 - 15 = 3x + 3x

75 = 6x

x = 75 / 6

x = 12 3/6

x = 12 1/2

= 12.5

x = 12.5
