Question

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

Answer 1

i messed up "D" starts at "the diagnol of a rectangle"

Answer 2

Rectangle makes all angles are 90 degree
