A is equal to 92 degrees.
In similar triangles, the angles are all the same. So first you have to look for the placement of the letters in the congruence statement. Since ABC = PQR, we know that the first letters (A and P) are congruent. The same can be said of the middle letters (B and Q) or the end letters (C and R).
Since P is equal to 92 degrees and A is equal to P, then we know A is equal to 92 degrees.
