Answer:
A
Step-by-step explanation:
Under a reflection in the x- axis
a point (x, y ) → (x, - y )
Under a rotation about the origin of 90°
a point (x, y ) → (- y, x )
Under a reflection in the y- axis
a point (x, y ) → (- x, y )
Under a rotation of 180°
a point (x, y ) → (- x. - y )
Here A(3, - 5 ) → A'(3, 5 ) → A
The length of HJ is 3.5 cm
Two geometric figures are said to be congruent, or to be in the relation of congruence, if it is possible to superpose one of them on the other so that they coincide throughout.
Given:
AB = 3.5 cm, BC = 2.4 cm, and AC = 4.2 cm
As, ΔABC ≅ ΔHJK
So,
AB = HJ
BC = JK
AC = HK
Thus, HJ= AB = 3.5 cm

i think A=20
A=pq/2 =4·10/2 =20
Hope i helped

The slope is 2/3
m=y²-y1/x²-x¹
m=6-4/5-2
m=2/3
