Find an expression equivalent to 18 + 30. factors of 18: 1, 2, 3, 6, 9, 18 factors of 30: 1, 2, 3, 5, 6, 10, 15, 30 18 + 30 = 6(3 + 10)

answer: a

step-by-step explanation:

if xy ~ yz therefore xy would be the same length as yz

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)
