Sin(x) =1/10
So Cos x is not known
Hence Tan(x) = Sin(x)/Cos(x)
= 1/10/cos(x)
so cos(x)/10
D a rhombus has Diagonals that are not necessarily perpendicular
Step-by-step explanation:
Using the vertical line test, we can see which lines are functions, and which are not. If a vertical line were to hypothetically appear, would it touch more than one part of the line? If so, it is not a function.
The lines outlined in a black box are the correct answers.
