Answer:

Step-by-step explanation:
We have been given that triangle VAT is congruent to triangle BDT. We are asked to find the length of segment BT.
Since both triangles are congruent, therefore, their corresponding sides will be equal by the definition of congruence.

By the definition of congruence:



Since the length of side VT is 6.3 units, therefore the length of BT is 6.3 units as well.
