Diketahui segitiga ABC siku-suku di titik C dgn panjang AC=2 BC=4 dan jika sudut BAC=Alfa. Tentukan perbandingan trigonometri sudut alfa. Tolong jawab dong mump

BC = 4, AC = 2
AB = √4^2+2^2 = √16+4 = √20 = 2√5

Sin a = 4/2√5 = 2√5/10
Csc a = 2√5/4 = √5/2
--------------
Cos a = 2/2√5 = √5/5
Sec a = 2√5/2 = √5
--------------
Tan a = 4/2 = 2
Cot a = 2/4 = 1/2

Semoga membantuu :)
