Please explain the rest with the two boxes

Answer 1

From the segment addition postulate with respect to line segment DG, we have that; x = 7

How to use the segment addition postulate?

The segment addition postulate states that if "B" is between "A" and "C", then the length of segment "A" "B" + the length of segment "B" "C" equals the length of segment "A" "C."

AB + BC = AC

Applying the segment addition postulate to line segment DG, gives us;

DO + OG = DG

Thus;

4x - 3 + 2x + 21 = 60

6x + 18 = 60

6x = 60 - 18

6x = 42

x = 42/6

x = 7
