Which of these to 3x ^ 2 + 14 = - 37x A : x= +\- 17i
B: x = +- 17 +I
C: x= t/-i radical 17
D:x =+\- 17i^2

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
