Step-by-step explanation:
cos A = 16/20 = 4/5
tan A = 12/16 = 3/4
sin A = 12/20 = 3/5
This question is incomplete. Can you maybe add more information?
Answer:
or
Step-by-step explanation:
Note that .
Also, note that .
So, the inequality is really equal to .
We can then add to both sides to get .
So, the solution is , or in interval notation,
The 7 is in the Ones place
I believe that x=20 from the math i did hopefully its helpful.
