Elp me BROS! its GEOMETRY 10 points REWarded, best answer gets BRAILIEST!

Arc BD is 6.1 degrees

Step-by-step explanation:

So if 5.7 is in miles, the observer is 30096 feet above sea level, cruising height.

Solution.

Segment BC and DC are tangent to the circle,

so angles CBA and CDA are 90 degrees, hence

Triangles CBA and CDA are right triangles,

with

AC = 4005.7 miles

cos CAB = AB/AC = 4000/4005.7 = 0.9985770

angle BCA = arc cos(0.9985770) = 3.057 degrees

Arc BD = central angle BAD = 2*angle BCA = 6.114 degrees

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)

the answer is b.)
