Figure JKLM shows the top surface of a box shaped as a rectangle with segment JL as its diagonal. The measure of angle KJL is (x + 7) degrees and the measure of angle MJL is (2x – 1) degrees.

Which property of rectangles is used to write the equation (x + 7) + (2x – 1) = 90 and solve for x?
Answer

A) The opposite sides of a rectangle are parallel.

B)The opposite angles of a rectangle are equal.

C)The adjacent angles of a rectangle are supplementary.

D)The diagonal of a rectangle divides the angle at the vertex into two complementary angles.
