1). Sin is any act regarded as a transgression of divine law, especially a willful or deliberate violation of some religious or moral principle.
2). 'Sin' is an abbreviation for 'sine'. In a right triangle, the 'sine' of one of the acute angles is the ratio of the length of the side opposite the angle to the length of the hypotenuse.

Sin is used to find the degree of an angle. Sin is the opposite over hypotenuse.

In mathematics, 'sin' refers to the sine function, which is the ratio of the length of the side opposite an angle to the length of the hypotenuse in a right triangle. The sine function is calculated as sin ( θ ) = Hypotenuse Opposite ​ . It is essential in geometry and has various applications in physics and engineering.

Jawaban:Diketahui:- 5 pasang sandal + 4 topi = Rp345.000- Harga 2 pasang sandal = Harga 3 topi Ditanya:- Harga sepasang sandal caranya:1. Buat persamaan:- Persamaan 1: 5S + 4T = 345.000 (S adalah harga sandal, T adalah harga topi)- Persamaan 2: 2S = 3T --> T = (2/3)S2. Substitusikan nilai T dari Persamaan 2 ke Persamaan 1:- 5S + 4((2/3)S) = 345.000- 5S + (8/3)S = 345.0003. Samakan penyebut dan sederhanakan:- (15/3)S + (8/3)S = 345.000- (23/3)S = 345.0004. Cari nilai S (harga sepasang sandal):- S = (345.000 * 3) / 23- S = 1.035.000 / 23- S = 45.000 maka, harga sepasang sandal yaitu Rp45.000,00

Jawab:Penjelasan dengan langkah-langkah:Untuk menghitung harga sepasang sandal, kita perlu menggunakan sistem persamaan linear. Diketahui 5 sandal (S) + 4 topi (T) = Rp345.000 dan 2S = 3T. Substitusikan T = 2S/3 ke persamaan pertama: 5S + 4(2S/3) = 345.000 menjadi 5S + 8S/3 = 345.000, lalu 15S/3 + 8S/3 = 345.000, sehingga 23S/3 = 345.000, akhirnya S = Rp45.000.Langkah-langkah penyelesaian:Buat persamaan:5S + 4T = 345.000 (Persamaan 1)2S = 3T (Persamaan 2)S = harga 1 pasang sandalT = harga 1 topiUbah Persamaan 2 untuk mencari T:Dari 2S = 3T, maka T = 2S / 3Substitusikan nilai T ke Persamaan 1:5S + 4(2S/3) = 345.0005S + 8S/3 = 345.000Sederhanakan dan selesaikan untuk S:Untuk menyederhanakan, kita samakan penyebutnya:(15S/3) + (8S/3) = 345.00023S/3 = 345.00023S = 345.000 * 323S = 1.035.000S = 1.035.000 / 23S = 45.000Jadi, harga sepasang sandal adalah Rp45.000.
