Quadrilateral ABCD with coordinates A (-6, 3). B (-4, 6), C (-2,5), and D (-3, 2) is mapped
onto quadrilateral A'B'C'D' with coordinates
A' (8, 1), B' (6, 4), C' (4, 3), and D' (5, 0). Are the
quadrilaterals congruent?

The answer would be a

Hello! i hope this
since the cosine is the ratio of the adjacent side to the hypotenuse, you can see that cos 60° = ½. answer. according to the property of cofunctions (topic 3), sin 30° is equal to cos 60°. sin 30° = ½.

The skating rink rented 872 pairs of skates during april and may.why? : if the skating rink rented three times the pair of skates in april during may, they rented 654 skates. 218 x 3 = 654then, if they want to know how many they rented during both april and may, then you just add 654 (may) and 218 (april) to give you 872 pairs of skates for both months.654 + 218 = 872hope this !
