On a coordinate plane, 2 triangles are shown. the first triangle has points a (negative 2, 1), c (negative 4, 1), and b (negative 3, 4). the second triangle has points a prime (1, negative 2), b prime (4, negative 3), and c prime (1, negative 4). what is the rule for the reflection? ry=x(x, y) → (–y, –x) ry=–x(x, y) → (–y, –x) ry=x(x, y) → (y, x) ry=–x(x, y) → (y, x)

Abilliard ball is struck by a cue. it travels 1 0 0 cm 100cm before ricocheting off a rail and traveling another 1 2 0 cm 120cm into a corner pocket. the angle between the path as the ball approaches the rail and the path after it strikes the rail is 4 5 ∘ 45 ∘ . how far is the corner pocket from where the cue initially struck the ball? do not round during your calculations. round your final answer to the nearest centimeter.
