Answer:
Step-by-step explanation:
draw a line AB
create a 90º from both end
join the bisected lines from both end to A, B and from the top respectively
Multiply numerator and denominator by sin(x) * cos(x), getting:
((sin(x) * cos(x)) - cos^2(x) / (((sin^2(x)) - (sin(x) * cos(x))) =
(cos(x) * (sin(x) - cos(x)))
------------------------------------
(sin(x) * (sin(x) - cos(x)))
and after you cancel the two identical terms (sin(x) - cos(x)), you have:
cos(x)
----------- = cot(x) <--------------- Answer
sin(x)
Answer:
59 and 79
Step-by-step explanation:
59+79=138
59 is 20 less than 79 so it works
Answer:
126.
Step-by-step explanation:
One way to do this is to see if 126 is divisible by 6,9 and 18. If so then the LCD is 126.
Use your calculator to check.
It is 126.
The total cost, including the deposit, would be $2,750. $500*5=$2,500 $2,500+$250=$2,750
