Answer:
x=31.6
Im not sure since i have not taken a trig course yet, but i know the basics:
Tangent is opposite over adjacent, and in respect to this angle, (31 degrees) the opposite side is 19 and adjacent is x.
Tan(31) = 19/x
Solve for x...use a calculator to find tan(31)

Answer:
A.
Step-by-step explanation:
From the given information:
If A = m × n matrix
where;
b is a vector in
Then; the statement that doesn't fit and is not related to the other three from the given options is Option A.
This is because the statement in Option A appears to be inconsistent. For the model Ax=b to have a solution, A must be non-singular and b must be in A's column space.
Option c and d are equivalent, also option b and c are equivalent.
