@texaschic101 Please answer this ^^ question.
I found all options to be wrong.

Answer 10

your answers look good except for Q4,

Answer 11

ok, thank you!
I re-did number 4 and got answer C. Is that right?

Answer 12

C is right, for anybody who finds this article later. :)

Answer 13

yes,4 C

Answer 14

@phi
Please explain me Q2 ??

Answer 15

*Omit ??
XD

Answer 16

Right triangle ABC with AB measuring 5, AC measuring 6, and BC measuring 8.

cot right angle triangle B equals fraction 6 over 5
csc right angle triangle C equals fraction 3 over 4
cot right angle triangle C equals fraction 8 over 5
csc right angle triangle b equals fraction 4 over 3

First, notice they cheated. They say the longest side (hypotenuse) is 8
in a right triangle we know a^2 + b^2 = c^2 so we expect
5^2 + 6^2 = 8^2 --> 25+36= 64 or 61=64 which is close, but not true.
