∆ABC ≅ ∆QRS .If AB = QR, BC = RS, ∠ABC = 56 degrees and ∠RQS = 67 degrees, what is the measure of ∠RSQ

Answer:
57 is the answer
Step-by-step explanation:
If Angle ABC is congruent to Angle QRS that means that they are supplementary (the measure of two angles is equal to 180°)
Solution:
m Angle ABC + m Angle RQS + m Angle RSQ = 180°
56° + 67° + m Angle RSQ = 180°
123 + m Angle RSQ = 180°
123 - 123 (cancel it out)
180 - 123 = 57
The answer is 57
