| **In a triangle, two sides are equal, and the third is two times shorter than each of them. Find the lengths of the sides of the triangle if its perimeter is 75 cm. Thank you guys in advance, you need to solve the equation method.**

Let the third side be equal to x centimeters, then each of the equal sides is equal to 2x, since it is twice as large. The perimeter of a triangle is equal to the sum of the lengths of all its sides, we draw up an equation, we get:

2x + 2x + x = 75;

5x = 75;

x = 15 centimeters – the third side, which means the other two 15 * 2 = 30 centimeters.

Answer: 30, 30 and 15.
