Answer:

sec ∅ = 5/4

cosec ∅ = -5/3

cot ∅ = -4/3

Tan ∅ = - 3/4

sin ∅ = -3/5

cos ∅ =4/5

Explanation:

Given : -4y = 3x , x > 0

i.e. 3x + 4y = 0 , x >0

4y = -3x ∴ y = - 3/4 x

The values of trigonometric functions of ∅ are

Tan ∅ = opposite / adjacent

= - 3/4 ( given that y = slope which is = Tan ∅ )

now we will find the hypothenuse ( c )

c^2 = a^2 + b^2 = 9 + 16 = 25

therefore ; c = √25 = 5

hence the trig functions are :

sin ∅ = -3/5

cos ∅ =4/5

sec = 5/4

cosec = -5/3

cot = -4/3
