Numbers 9 10 11 and 12

9) Is D. 154

10) B. Supplementary

11) B. Perpendicular

12) A. J and K

Step-by-step 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.

Hope this helped.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
