<h3>
Answer: D. y = -x</h3>
======================================================
Explanation:
Point T is at (-2,1)
When we reflect it over the line x = 0, aka the y axis, we use the rule 
so T(-2,1) becomes T ' (2, 1). The x coordinate flipped in sign, while the y coordinate stays the same.
Then the final transformation is reflecting over y = -x using the rule 
. Therefore, the point (2,1) moves to (-1, -2) which is where T'' is located in the diagram.
You apply the same two transformations for the points R and S to get R'' and S'' respectively.
Note: A composition of two reflections, where the lines of reflection aren't parallel, form a rotation. In this case, we have a 90 degree counterclockwise rotation when going from triangle RST to triangle R''S''T''.

Answer:
103.5°
Step-by-step explanation:
Let "x" represent the missing angle.
Vertex formed = ½(the sum of the intercepted arcs) based on the intersecting chords theorem.
Therefore:
m<x = ½(195 + 12)
m<x = ½(207)
m<x = 103.5
MIssing angle is therefore 103.5°
