The correct answer would be A) Puberty.
Puberty
maturational, hormonal, & growth process occurring when reproductive organs begin to function & secondary sex characteristics develop
This can be solved using the
angle bisector theorem. Note that line segment AD is the angle bisector of triangle DAB from angle DAB. Therefore, we know that the ratios
![\frac{\text{AD}}{\text{CD}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAD%7D%7D%7B%5Ctext%7BCD%7D%7D)
and
![\frac{\text{AB}}{\text{CB}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7BAB%7D%7D%7B%5Ctext%7BCB%7D%7D)
are equal. Solving, we get
![\frac{\text{12.2}}{\text{7.8}}=\frac{\text{AB}}{\text{6.5}}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Ctext%7B12.2%7D%7D%7B%5Ctext%7B7.8%7D%7D%3D%5Cfrac%7B%5Ctext%7BAB%7D%7D%7B%5Ctext%7B6.5%7D%7D)
. Cross multiplying, we get
![79.3 = 7.8x](https://tex.z-dn.net/?f=79.3%20%3D%207.8x)
, and solving this equation we get
![x = 10.1666... \approx 10.2](https://tex.z-dn.net/?f=x%20%3D%2010.1666...%20%5Capprox%2010.2)
.
10.2 is your answer.
