Compare 4 x 105 and 5 x 103. a) 4 x 105 is 80 times larger than 5 x 103 b) 4 x 105 is 8 times larger than 5 x 103 c) 4 x 105 is twice as large as 5 x 103 d) 5 x 103 is 80 times larger than 4 x 105

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)
