Click on the element in the periodic table to
explore the atomic radii of elements from period 3
and group 17. fill in the missing values in the
table so you can compare the atomic radii of the
elements. after the table is filled in, compare the
values in each column.

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)
