What additional piece of information would you need to use the Side-Angle-Side Triangle Congruence Postulate to prove that △RQP ≅ △SQP?

Step-by-step explanation:

Given

△RQP ≅ △SQP

See attachment

Required

Additional information that shows that △RQP ≅ △SQP

△RQP and △SQP share a common side QP:

This implies that:

---- Side (S)

△RQP ≅ △SQP implies that:

---- Angle (A)

Lastly, we already established that △RQP and △SQP share a common side QP

Then remove point P, we have: RQ and SQ

This implies that:

--- Side (S)

Hence, the additional piece of information needed is:

a. she will receive a refund of $278.

step-by-step explanation:

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"
