In trigonometric ratios, the cos (x) = adjacent over hypotenuse.
Therefore, in the diagram, cos (55°) = s/q
To isolate q, divide both sides by s
cos (55°) / s = 1/ q
Then flip both numerators and denominators (raise both sides to the power of -1)
q = s / cos (55°)
Answer is D
True, for a contrapositive you switch the parts and then make them opposite, but the statement is still true.
The answer to question was to question it if you don’t answer your question about how you do that you have a question for you
