Good afternoon,
First side= 8cm Third side= x Second side= 2x-4
We know that the sume of the lenghts of any two sides must be greater than the third side, so:
First\,\,\,\,side \\ 2x-4 + x >8 \\ 3x>12 \\ x>4"> S eco n d s i d e + T hi r d s i d e > F i rs t s i d e 2 x − 4 + x > 8 3 x > 12 x > 4
Answer: Third side= x ; where: x>4 or (4,+infinity) ** Second side= 2x-4 ; where: x>4 or (4,+infinity)**

The problem is based on the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the third side. We have one side that is 8 cm and a second side that is 4 cm less than twice the third side. Let's denote the third side as x cm. Therefore, the second side can be expressed as 2x - 4 cm.
To find the possible lengths for the second and third sides, we will use the triangle inequality theorem:
x + (2x - 4) > 8: This simplifies to 3x - 4 > 8 or x > 4.
(2x - 4) + 8 > x: This simplifies to 2x + 4 > x or x > -4. Since side lengths cannot be negative, this inequality doesn't provide new information.
8 + x > (2x - 4): This simplifies to 8 + x > 2x - 4 or x < 12.
Combining these inequalities, the possible lengths for the third side (x) must be greater than 4 cm and less than 12 cm. Consequently, the length of the second side, which is 2x - 4, must be greater than 4 (2 4 - 4) cm and less than 20 (2 12 - 4) cm.

The possible lengths for the third side of the triangle, x, must be between 4 cm and 12 cm ( 4 < x < 12). Correspondingly, the second side can range from just above 4 cm to just below 20 cm as calculated from the value of x. Thus, the second side is (4, 20) depending on x's value.

Jawaban:untuk membina nasionalisme, perlu dihindari sikap yang melemahkan rasa kebanggaan, persatuan, dan penghargaan terhadap budaya serta nilai-nilai bangsa Indonesia. Sebaliknya, fokuslah pada pendidikan, penghormatan, dan pelestarian nilai-nilai kebangsaan
