The cook took out 54.8 grams of butter, she then found out that she took out 6.9 grams of butter more than she need. How much butter did she need?

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

i believe that the answer is

b. y-1=-2(x-4)

hope this !
