Which transformation of figure a results in figure a'? a reflection across the y-axis a reflection across the x-axis a clockwise rotation of 90° about the origin a translation 12 units right and 2 units down.

A translation 12 units right and 2 units down.

Step-by-step explanation:

Given : Figure A and figure A'.

To find : Which transformation of Figure A results in Figure A'.

Solution : We have given that

Parent Triangle A with coordinates ( -6 ,-3) ; ( -4 ,-5) ; ( -8 , - 4)

Transformed triangle with  coordinates ( 6 ,-5) ; ( 8 ,-7) ; ( 4 , - 6)

We can see from the coordinates

( -6 +12 ,-3-2) = ( 6 ,-5)

( -4+ 12 ,-5 -2) = ( 8 ,-7)

( -8 + 12 , - 4 -2) =  ( 4 , - 6).

Therefore, A translation 12 units right and 2 units down.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
