Hello,
For the first question, congruent triangles have congruent corresponding angles and sides. For option choice A, MN corresponds with PQ, not PR, so it is incorrect to conclude that they are equal. The answer is A.
For the second question, we are given two angles and an not included side, so it would be AAS.
The answer is A, I believe.
Hope this helps!

Add them together then add 10,000
I = let
I= 300*.06*.5
I= $9.00
