determine algebraically the maximum number of adult-sized sweatshirts she can purchase.

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)

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2
