What is the solution to the system? 2x+y=9 x+2z=-3 2z+3z=15

answer: a

step-by-step explanation:

10.2 units

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft

b is the correct answer
