10.) obtuse
11.) right
12.) acute
13.) complementary
14.) neither
15.) supplementary
16.) neither
17.) measure of angle O = 95 degrees
18.) measure of angle J = 68 degrees
19.) supplementary, x = 152 degrees
20.) complementary, x = 24 degrees
21.) supplementary, x = 46 degrees
The measurement on #21 is not very clear, but my answer is based off the assumption that the given angle is 134 degrees.
