Lee is thinking of two Numbers,the product is 18. the quotient is 2
defon
X, y - the numbers

The product is 18.
xy=18

The quotient is 2.
\frac{x}{y}=2 \ \ \ |\times y \\
x=2y

Substitute 2y for x in the 1st equation:
2y \times y=18 \\
2y^2=18 \ \ \ |\div 2 \\
y^2=9 \\
y=\pm \sqrt{9} \\
y=3 \ \lor \ y=-3 \\ \\
x=2y \\
x=2 \times 3 \ \lor \ x=2 \times (-3) \\
x=6 \ \lor \ x=-6 \\ \\
(x,y)=(6,3) \hbox{ or } (x,y)=(-6,-3)

The numbers are 6 and 3 or -6 and -3.

Answer is A. 30 degree

as we know that two prependicular lines have 90 degree angle between them

and similarly a horizontal line has angle zero degree.

the angle of pic shown is approximately 30 degree as it lies between prependicular and horizontal nature of lines

but as we can see that it is close to horizontal nature of the line that's why its approximate angle is 30 degree.
