Stacked Right Triangles

Question

There are two triangles ABC and A’B’C’. Where A+A’=57°, B=B’=90°, C=90°-A, C’=90°-A’, BC=20, A’B’=150, and AC=A’C’. What is the angle of A’?

Answer 1

This is an inconsistent system and the info. Is Contradictory

A(90-a)= A'( 90- A')

And

a'= 57-a

The result is A=32.25 and A' = 24.75

But since a'b'=150, then b'= 6.060606....

This contradicts b'=90
