Line segment BD passes through the center of circle C, BH = a, and HD = 8. Circle C is shown. Chords B D and F G intersect at point H. Chord B D goes through center point C. The length of B H is a, the length of H D is 8, the length of F H is 6, and the length of H G is 6. Angle B H G is a right angle.

What is the length of the diameter?

4.5 units
8 units
12 units
12.5 units

12.5 units

Step-by-step explanation:

if the line down the center is 8 and the diameter is in the middle then both those sides need to be 8 and so the 6's on both sides of the diameter have to stay the same but they only change a little for 6+6 is 12 but the length gets longer since it moved farther down 

answer D 12.5

side xy = 10

sin(x) = 4/5

cos(x) = 3/5

tan(x) = 4/3
