Question

Determine the value of cot 36 degrees

Answer 1

option D

Explanation:

cot(36°)

Cot can be written as
`(1)/(tan)`

So cot(36)=
`(1)/(tan(36))`

Tan is positive in first and third quadrant

`(1)/(tan(36))` gives us positive value because 36 degree is in first quadrant.

Use calculator to find the value of
`(1)/(tan(36))`

`(1)/(tan(36))`= 1.37638192

option D

Answer 2

Cot( \theta) = 1/tan( 1\theta)
Tan (36o) = 0.7265
1 / tan(36o) = 1.3765
