Solve it like a normal equation, but with < instead of =
9k - 2 < 3k + 10
-3k -3k
_____________
6k - 2 < 10
+2 < +2
_____________
6k < 12
÷6 ÷6
_____________
k < 2 is your final answer :)
It is a supplementary angle. D because the add up to 180.
205.2 square feet
Convert 90% to a decimal. You get .9 Multiply 228 by .9 to find what 90% of 228 is. You should get 205.2.
Answer:
sin(-a)= -15 /17
Step-by-step explanation:
Alright, lets remember that sin(x) is odd function, which means that
wherever you watch an expression like this: sin(-a), you can use the odd functions property, and turn it like the following
sin(-a)= - sin(a)
Now, other thing to remember: 
So, we can obtain any value for sin(x) function starting from the opposite function, cos(x), using the following:

So, if cos(a)= - 8 / 17, using the above equation we obtain the value for sin(a)

Using the odd function property, we get the following result
sin(-a)= - sin(a) = -15/17
