Penjelasan dengan langkah-langkah:

mencari sisi alas

x = √30² - 10²

x = √900 - 100

x = √800 = 20√2

sin α = depan/miring = 10/30 = 1/3

cos α = samping/miring = 20√2 / 30 = 2√2/3

tan α = depan/samping = 10/20√2 = 1/2√2 = √2/4

secan α = 1/cos α = 1/2√2/3 = 3/2√2

cosec α = 1/sin α = 1/1/3 = 3

cot α = 1/tan α = 1/ 1/2√2 = 2√2
