3 (costheta , sintheta). This is because point P is in the first quadrant, and in the first quadrant, both the x and y values are positive. Option 1 simply switched sin and cos, which is wrong. Option 2 switched sin and cos as well as takes place in the 4th quadrant (-x and -y). The 4th option is also in the 4th quadrant.
I hope this Helps!
<span>x=theta
so we know that tanx = sinx/cosx
therefore is tanx = 4/3 and sinx = -4/5
we can set up an equation to find cosx
so 4/3 = (-4/5)/cosx
we can multiply x to have cosx(4/3)=-4/5
we can then divide 4/3 over so we have
cosx = (-4/5)/(4/3)
therefore, cos x = -3/5

there is the answer
i hope this help
Answer: 4 miles
Step-by-step explanation: what you need to is 5+3 which is 8 then 12-8 what is 4 so he needs to run 4 miles on Thursday
Answer:
Step-by-step explanation:
Let x = the number of $20 bills.
Then x + 6 = the number of $5 bills and
20x + 5(x + 6) = 455
x = 17 = number of $20 bills
x + 6 = 17 + 6 = 23 = number of $5 bills

OK.
