Answer:

sinθ=4/5 and tanθ=4/3

Step-by-step explanation:

Given that,

cosθ=3/5

Base/Hypotenuse=3/5    {cosθ=base/hypotenuse}

Therefore,it is clear that the ratio of base and hypotenuse is 3:5

So, we can say that,

Base=3x units  and  Hypotenuse=5x units

According to Pythagoras theorem:-

(Hypotenuse)²=(Base)²+(Perpendicular)²

∴(Perpendicular)²=(Hypotenuse)²-(Base)²

Now, putting values:-

(Perpendicular)²=(5x)²-(3x)²

(Perpendicular)²=25x²-9x²

(Perpendicular)²=16x²

Perpendicular=√16x²

Perpendicular=4x units

∴sinθ=Perpendicular/Hypotenuse

 sinθ=4x/5x=4/5

 tanθ=4x/3x

 tanθ=4/3
