If polygon mast with coordinates m(-3,-1), a(-3,2),s (-1,3) and t (1,1) is reflected across x=-3, then which of the following coordinates represent the vertices of the polygon man's'? select all that apply

Let 'a' be the point and 'A' be the reflection of point 'a' through line x= -3

we know, (a+A)/2 (mid point of line aA) should lie on line x= -3

so by using this, we calculate vertices of reflected shape of MAST, we get

(-3,-1), (-3,2),(-5,3) and (-7,1)

Answer with explanation:

→The Polygon MAST has coordinates "M(-3,-1), A(-3,2),S (-1,3) T (1,1)".

Now, the polygon is reflected across , line ,x= -3.

Now, the Meaning of reflection is that ,the Shape and size of Image before and after Reflection does not change.

And when you , reflect the polygon which is a quadrilateral having vertices M, A, S, and T, the perpendicular distance from line , x=-3, from each of the vertices of the Quadrilateral,Called Pre-Image, will be same from each of the Vertices of the polygon after Reflection Called Image.

When , "polygon MAST is reflected across line", x=-3, the vertices of Image M'A'S'T' will be

M(-3,-1)→M'(-3,-1)

A(-3,2)→A'(-3,-2)

S(-1,3)→S'(-5,3)

T(1,1)→T'(-7,1)

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 .
