Question

If 4 tan thita=3 then prove that sin thita cos thita = 12/25

Answer 1

Answer:

sin theta cos theta =12/25

Step-by-step explanation:

4tan theta =3 then tan theta= 3/4

we know that tan theta = opposite/adjecent

opposite side= 3

adjacent side =4

☆hypotenuse²=opposite ² +adjacent ²

x²=3²+4²

x²= 25

x=5

then sin theta =3/5

cos theta =4/5

And by multiplying sim theta cos theta we get

that 3/5×4/5=12/25

hence proved!!!!!
