Step-by-step explanation:
3 tan θ=4
tan θ=4/3
w.k.t sin θ/cos θ=tan θ
therefore sin θ=4
cos θ=3

Answer:
3 tan theta= 4
tan theta=4/3
p/b=4/3
By using Pythagoras theorem, we get
p^2 + b^2=h^2
(4)^2+(3)^2=h^2
16+9=h^2
25=h^2
h=root 25
=5
Now,
3sin theta + 2cos theta÷3sin theta - 2cos theta
=3×p/h +2×b/h÷3×p/h - 2×b/h
=3×4/5+2×3/5÷3×4/5-2×3/5
=12/5+6/5÷12/5-6/5
=18/5÷6/5
=18/5×5/6 ( since 18 is cancelled by 6
and 5 is cancelled by 5)
.
. . Answer of this question is 3.
