The law of cosines is
c= square root of a^2 + b^2 - 2ab cos c
the law of sines is
a = b(sin a /sin b)
Seria 25/5 por que si lo divides seria 5X5=25 ok a ver si te sirve
true because if you add up 4 90°you get 360
Answer:
Step-by-step explanation:
Amplitude is twice the coefficent of the sine function. In this case, 
Period is
divided by the coefficent of x, in this case, 
Phase shift, is how much you sum or subctract from x inside the sine, in this case
.
Midline you get by hiding the sine and reading what's left, in this case, -4.
