The sides of a triangle are proportional to the numbers 6 5 4.

The sides of a triangle are proportional to the numbers 6 5 4. The smaller side of a similar triangle is 3.6. Find the other sides of the second triangle

1. Let’s denote the coefficient of similarity through x.

2. Let’s define the sides of this triangle:

6x, 5x and 4x.

3. Since the smaller side of such a triangle is 3.6, compose and solve the equation:

4x = 3.6;

x = 3.6: 4;

x = 0.9.

4. The coefficient of similarity is 0.9.

5. What is the length of the middle side of the triangle?

5 * 0.9 = 4.5.

6. What is the large side of the triangle?

6 * 0.9 = 5.4.

Answer: The sides of the triangle are 4.5 and 5.4.
