Answer 2

Step-by-step explanation:

Let theta = α

Given, cos theta=4/5 => cos α = 4 / 5

sin²α + cos²α = 1 => sin²α + (4/5)² = 1

sin²α = 1 - 16/25 = 9 / 25

=> sin α = 3 / 5

=> cosec α = 1 / sin α = 1 / 3/5 = 5 / 3

sec α = 1 / cos α = 1 / 4/5 = 5 / 4

tan α = sin α / cos α = 3/5 / 4/5 = 3 / 4

cot α = 1 / tan α = 1 / 3/4 = 4 / 3
