Question

If 17 sin a=8 find the value of 2 tan a/1+tan a^

Answer 1

Answer:

16/23

Step-by-step explanation:

17 sin a=8

=sin a =8/17

as we know that sin a=P/H

so,p=8 and H=17

after that ,we can easily find out

that the third side would be

√H^2 - p^2

=√289 - 64

=√225

=15

so ,we have hence found the base

which is 15

so, by putting value,

as we know that tan a=P/B

according to the question:

2×p/b/1+p/b

=2×8/15/1+ 8/15

=16/15/23/15

15 gets cut

so giving us answer= 16/23
