Answer:
x ≈ 54.8°
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan x = = = , then
x = ( ) ≈ 54.8° ( to the nearest tenth )
A'(0,-1), B'(1,0) , C'(3,-2), and D'(2,-3)
The coordinates of rectangle ABCD are A(-1,0), B(0,-1), C(-2,-3), (-3,-2).
The mapping for a rotation through 90° clockwise about the origin is
Therefore:
Therefore the image rectangle has coordinates:
The first choice is correct.
