Penjelasan dengan langkah-langkah:
alpha = sudut BCA
AB = 15
BC = 20
AC² = AB² + BC²
AC² = 15² + 20²
AC² = 225 + 400
AC² = 625
AC = V625
AC = 25
a. Sin BCA = AB/AC = 15/25 = 3/5
b. Cos BCA = BC/AC = 20/25 = 4/5
c. Tan BCA = AB/BC = 15/20 = 3/4
d. Csc BCA = AC/AB = 25/15 = 5/3 = 1⅔
e. Cot BCA = BC/AB = 20/15 = 4/3 = 1⅓
