What is being constructed based on the markings in the following diagram? Inscribed regular hexagon
inscribed equilateral triangle
perpendicular line through a point off a line
perpendicular line through a point on a line
thank you :)

  perpendicular line through a point on a line

Step-by-step explanation:

The circle centered at C seems intended to produce point D at the same distance as point B. That is, C is the midpoint of BD.

The circles centered at B and D with radius greater than BC seems intended to produce intersection points G and H. (It appears accidental that those points are also on circle C. As a rule, that would be difficult to do in one pass.)

So. points G and H are both equidistant from points B and D. A line between them will intersect point C at right angles to AB.

Segment GH is perpendicular to AB through point C (on AB).

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth
