X=number total of student at the school.
70% of x=161

0.7x=161
x=161/0.7=230

There is a designated formula for this circle drawing. This is a secant-secant scenario, and in this case, the formula is:
CD(CD+X)=CB(CB+AB)
Plug the values in.
AB=42
BC=18
CD=4
4(4+x)=18(18+42)
Solve for x.
16+4x=1080
4x=1064
x=266
Your answer is C
