Jake is going to call one person from his contacts at random. He has 30 total contacts .16 of those contacts are people he met at school.

Im sorry but your question needs some more detail ;w;

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)

just sum

10 + 10 = 20
