Question

If sin x=- 12/13 and sin y =4/5 , where pie/2 <x<pie and 0 <y <pie/2, find the values of
(i) sin(x + y), (ii) cos (x + y), (3) tan (x - y)​
step by step​

Answer 1

Answer:

Step-by-step explanation:

if x belongs to the interval (pi/ 2 , pi) , then sin x > 0 and therefore sinx CANNOT be equal to - 12 / 13!!!!!!!!

so please correct your question and then i can solve it
