Answer:
13) <3 = 130 degrees and <7 = 130 degrees.
<3 and <7 are corresponding angles.
14) <5 = 47 degrees and <8 = 47 degrees
<5 and <8 are alternate interior angles.
15) <4 = 65 degrees and < 9 = 65 degrees
<4 and <9 are alternate interior angles.
16) <6 = 125 degrees and <8 = 180-125 = 55 degrees
<6 and <8 are supplementary angles
17) <3 and <4 are not complementary angles.
