Answer:

AB is 16; DG is 18

Explanation:

Given:

  • AC = 3x+2
  • GC = y +1
  • BC = 4x
  • DC = 2y -7
  • AC = BC, DC = GC

Find:

AB, DG

Solution:

Using the given expressions in the equations relating the line segments, we have ...

AC = BC

3x +2 = 4x

2 = x . . . . . . . . . subtract 3x

AC = BC = 4(2) = 8

AB = AC +BC = 8 +8 = 16

__

DC = GC

2y -7 = y +1

y = 8 . . . . . . . add 7-y

DC = GC = (8) +1 = 9

DG = DC +GC = 9 +9 = 18

Leg AB is 16; leg DG is 18.

Additional comment

The geometry described in this problem statement is impossible. If the 39° angle is accurate, then the angle where the legs cross is 95.9°. If the 101° angle is accurate, then the longer leg makes an angle of about 36.7° with the table top.
