Question

maths trignometry class 10 very hard , can u solve

Answer 1

I Think answer is option A......

Answer 2

5tantheta - 3costheta/5sintheta +3costheta=?

(tan theta=3/4, sin theta=4/5)

(-3costheta and 3costheta will be getting canceled)

So,we get

5tantheta/5sintheta= 5 will be getting canceled in both.

So, we Get

3/4÷4/5

=3×4/4×5

=12/20=

=3/5 .

So,

5tantheta-3costheta/5sintheta+3costheta=3/5.
