Answer 1

Step-by-step explanation:

Answer it 4/5

Hope it helps:)

Answer 2

Answer: sinθ= -4/5

Step by step explanation:

tanθ = -4/3 = height/base

By pythagoras theorem,

(Hyp.)² = (-4)² + (3)²

(Hyp.)² = 16+ 9 = 25

(Hyp.) = √25 = 5

Then,

Hypotenuse = 5

Height = -4

Base = 3

sin θ = height/hypotenuse

 

sin θ = -4/5
