Answer:
9- their sum is 90
10- every angle of a rectangle is a right angle.
when it is intersected into two angles their sum is 90
11-PKQ=NKM vertically opposite angles
alsoNKM+MKL=90
X+14+X=90 COMPLEMENTARY ANGLES
W
2X=76
X=38
PKQ=NKM=X+14=52
14- the sum of complementary angles is 90
vertically opposite angles are equal
