The Real Number line is just a one dimensional line, if you are at any point on the line you can only move

in two directions

1) positive direction - to the right

2) negative direction - to the left

If E is at -2 and EG = 9, Then point G is 9 units from E since the length of EG is 9

9 units to the right is

-2 + 9 = 7

9 units to the left is

-9 - 9 = -11

Thus, there are only two possibilities for G, 7 or -11 Answer

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
