Answer:
TA = 6 units
GT = 10 units
Step-by-step explanation:
Angle G is common to both triangles, so that's a congruent angle.
Since RT is parallel to EA,
Angle R = Angle E
And
Angle T = Angle A
When two triangles have the same distribution of angles, they are similar (by AAA).
Therefore GRT and GEA are similar
GE/GR = GA/GT
8/5 = 16/(16-x)
16-x = 16 × 5/8
16 - x = 10
x = 16 - 10
x = 6
GT = 16 - x = 16 - 6 = 10
