Answer: 
=========================================================
Explanation:
Use the pythagorean trig identity 
and plug in the fact that 
Isolating sine leads to 
. I'm skipping the steps here, but let me know if you need to see them.
The result is negative because we're in quadrant 4, when y < 0 so it's when sine is negative.
Therefore,
i got:
n = -1 + 3/x
x = 3/n + 1
not sure if this helps but i hope it does somehow
Answer:
1)b=-4
2)k=4
3)can u explain what #3 and 4 say
4)?
5)0/ no solution
Step-by-step explanation:
Mary = (1/3)x
Erin = x - 8
John = x
Here is your equation:
(1/3)x + (x - 8) + x = 267
Take it from here.
To simplify i^82, divide 82 by. the answer is 20 with remainder 2
