Question

anyone answer this question soon very urgent​

Answer 1

Answer:

cos@/sin@=1/2

sin@=2cos@

then

8cos@-2sin@/4cos@+2sin@

=8cos@-4cos@/8cos@

=4cos@/8cos@

=1/2

ok

follow me

gys

Answer 2

Answer:

cos@:sin@=1:2 ;

cos@=1k,sin@=2k (8cos@-2sin@):(4cos@+2sin@)= = (8×k-2×2k):(4×k+2×2k) =4k:8k =1:2
