Answer:

Sin theta =4/5

Step-by-step explanation:

Cos theta=base/HYPOTENUSE=3/5

Hence

From here we get

Base=3,HYPOTENUSE =5

By Pythagoras theorem

Hypotenuse ²=base²+perp²

5²=3²+perpendicular²

25=9+perp²

Perp²=25-9

Perp ²=16

Perp=4(taking sq root on both sides)

Now

Sin theta=perp/hyp=4/5
