Answer:
B'(1,5)
Step-by-step explanation:
On reflection about the x-axis the transition rule followed is
[tex]0(x,y)\rightarrow O'(x,-y)[/tex]
Given:
[tex]\triangle ABC[/tex] is reflected on [tex]x[/tex]-axis.
Points:
[tex]A(3,-1) ,\ B(1,-5)\ and\ C(-2,-2)[/tex]
New point [tex]B'[/tex] can be given as:
[tex]B(1,-5)\rightarrow B'(1,-(-5)) =B'(1,5)[/tex]
