Answer:
1 4 2
Step-by-step explanation:
The two equal sides of isoscles triangle = x+2 cm
Since there are two sides, x+2 repeats twice
The third unequal side = x+6 cm
Perimeter of triangle = 385 cm
Sum of all three sides = perimeter of triangle
x + 2 + x + 2 + x + 6 = 385
3x + 10 = 385
3x = 385 - 10
3x = 375
x = 375/3
x = 125
So the two equal sides = x + 2 = 125 + 2 = 127
The third side = x + 6 = 125 + 6 = 131
Perimeter = 127 + 127 + 131 = 385
Hence proved
