Answer:
Step-by-step explanation:
5y - 2y = 10
3y = 10
y = 10/3 = 3⅓
Answer:
Using trigonometric ratio:


From the given statement:
and sin < 0
⇒
lies in the 3rd quadrant.
then;

Using trigonometry identities:
Substitute the given values we have;

Since, sin < 0
⇒
now, find
:

Substitute the given values we have;

Therefore, the exact value of:
