Identify which property will prove these triangles congruent

Ab based on the given diagram, if m_1 = 60° then m 2 = 30 60 90 180

Hundred and tens tables to make 430 in five different ways

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.
