1. If we drop two heights on the lower base, it will be divided into three segments. One is equal to the top, and the other two are equal (18 – 6) / 2 = 6 centimeters.

2. In a right-angled triangle, the lateral side is the hypotenuse and it is twice as large as the leg, which is opposite to 30 °. Determine the length of the side.

6 * 2 = 12 centimeters.

Answer: 12 centimeters.
