One side of the triangle is 2cm smaller than the other and half the size of thirds.

One side of the triangle is 2cm smaller than the other and half the size of thirds. Find the sides of the triangle if its supervisor is 22 cm.

Let’s denote by the unknown variable x centimeters – the first side of the triangle,

Then x + 2 centimeters is the second side of the triangle,

Then 2x centimeters is the third side of the triangle.

The sum of all sides of the triangle (perimeter) is 22 centimeters. Let’s make the equation:

x + x + 2 + 2x = 22;

4x = 20;

x = 5 centimeters – the first side of the triangle,

5 + 2 = 7 centimeters – the second side of the triangle,

5 * 2 = 10 centimeters – the third side of the triangle.
