Step-by-step explanation:

for the relationship of lengths of internal chords the product of both segments of a chord is equal for all intersecting chords.

in our case

(x+8)×8 = 7×16 = 112

8x + 64 = 112

8x = 48

x = 6

so, D-F = x + 8 = 6 + 8 = 14

so, C is correct

The ratio of men to women in a certain factory is 3 to 4. There are 210 men.
WARRIOR [948]
There are 490 workers

3/4 = 210/x
Cross multiply, 210x4 and 3x
You're then left with 3x = 840, divide both sides by 3
This answer is 280 and represents the amount of female workers

Then just add 210 and 280, your answer is 490. Hope that helps!
