The image reads:

"Diketahui sebuah segitiga ABC siku-siku di B, memiliki panjang AB = 18. Tentukanlah panjang BC dan AC!"

Translation: "Given a right triangle ABC with a right angle at B, and AB = 18. Find the lengths of BC and AC!"

To solve this problem, we need more information, typically another side length or the angle values, to use trigonometry or the Pythagorean theorem effectively. Since only one side (AB) is given, additional information is necessary to proceed further.

Could you provide more details about the triangle, such as the length of another side or an angle?

Would you like to ask more questions or need any specific information? Here are some related questions you might find helpful:

1. What are the properties of a right triangle?
2. How is the Pythagorean theorem used in right triangles?
3. What trigonometric functions can be applied to find unknown sides in a right triangle?
4. How can we use the sine, cosine, or tangent ratios to find missing sides?
5. How do you calculate the hypotenuse in a right triangle?

Tip: In right triangles, if one of the legs and an acute angle are known, trigonometric functions can be used to find the other sides.
