Acomposition of transformations maps ? xyz to ? x"y"z". the first transformation for this composition is , and the second transformation is a 90° rotation about point x'.

Answer is reflection across line. When transformation maps X"Y"Z" .Then first transformation for this composition is , and the second transformation is 90° rotation about point X'.

Step-by-step explanation:

When you transform a point across a line y=x then x-coordinate and y-coordinate changes.

Similarly when you reflect a point across the line y=-x then signs are changed and both coordinate change places.

It is the first transformation across the line.

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

only 10/60 isn't equivalent

hope this : )
