Question

If 8tan x =15 then sinx-cosx is equal to

2 points

8/17

17/7

1/17

7/17

​

Answer 1

Step-by-step explanation:

tanx = 8/15

by pythagoras theorem :

The third side = √(64+225)

The third side = 17 units.

So sinx = 8/17

cosx= 15/17

So sinx- cosx= -7/17

So answer : -7/17

There is no such option in your question.
