△abc has interior angles with measures x°, 90°, and 65°, and △def has interior angles with measures y°, 65°, and 20°. using the given information, which statement is true? a the two triangles are not similar because x≠20 and there cannot be three congruent interior angels. b the triangles are similar because they each have an interior angle with measure 65°. c the two triangles are similar because y=90 . d the two triangles are not similar because the interior angles are congruent but the side lengths are different.

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
