The law of cosines is:
c² = a² + b² - 2abCos(C)
Therefore, in order to apply this law, we must know the value of two adjacent sides, represented by a and b here, and the value of their subtended angle, represented by C.
BD=90 DF=110 meaning BF=200
200/5x
X=40
Answer:
there is a pattern of 2 , 3 in each set of numbers
Step-by-step explanation:
Answer:
17, -3, -13, -18, -23
Step-by-step explanation:
Plug in the x side into the equation so
g(-4) = -5(-4) -3
g(-4) = 20-3
g(-4) = 17
Therefore that answer is 17
Then you do that for all of them, I don't have the time to do them all but that's the concept for all of them. Hope this helps and hopefully it's not too late. Sorry!
