Answer: 11/8 * 1/9 = 11/72
Step-by-step explanation:
Btw, * means multiply
It equals 11/72 because if you multiply the numerator 11*1, it equals 11. If you multiply the denominator, 8*9, it equals 72. So it equals 11/72, and it cannot be simplified. Hope this helps! :3

Step-by-step explanation:
Assuming tan = 2

tart off by rewriting tan

Combine in to a single fraction and factor out a

Finally just rewrite sin
2
(

Answer:
Step-by-step explanation:
Do you mean 3/7x or 3/(7x) ?
If 3/7x = 33 then x = 33·7/3 = 77
If 3/(7x) = 33 then x = 1/77
