The larger interior angle of a parallelogram is 90° more than its smaller interior angle. What is the measure of the smaller interior angle of the parallelogram?	Answers
A) 90 °	B) 75 °	C) 60 °	D) 45 °	E) 30 °

Rationale: let smaller be x , larger becomes x + 90 . . . total of all angles = 360 so 4 x + 180 = 360 and x = 45 answer : d
Answer: D
