Answer:
9) Is D. 154
10) B. Supplementary
11) B. Perpendicular
12) A. J and K
Explanation:
9) Supplementary angles equal 180 degrees. Complementary angels are 90 degrees. If angle A is 64; subtract 64 from 90. The difference is angle B.
90-64=26
If angle B is 26 degrees, subtract 26 from 180.
180-26=154.
10) Angle 1 and 2 equal 180 degrees, which is a supplementary angle
11) Lines AD and AC meet up to form a right angle. A perpendicular angle.
12) Parallel lines are two lines that never meet up.
