Answer:
The coordinates of triangle A"B"C" will become
A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )
Step-by-step explanation:
Original vertices of triangle ABC are ;
A ( -3, 5 ) B( 6, 9 ) C ( -4, -12 )
after reflection over x-axis
A( -3,-5 ) B( 6, -9 ) C( -4,12 )
when the triangle is rotated
x coordinates becomes -y while y coordinates becomes x
The coordinates of triangle A"B"C" will become
A( 5,-3 ) B( 9,6 ) C( -12 ,-4 )
