Answer:
D)  
Step-by-step explanation:
y = 12x.
A) x=8, so that y = 12(8) = 96.  It's on the line
B) x = 10, so that y = 12(10) = 120.  It's on the line
C) x = 15, so that y = 15(12) = 180.  It's on the line
D) x = 18, so that y = 18(12) = 216, not equal to 206.  So, the point is not on the line.

Answer:
see explanation
Step-by-step explanation:
Given 
tan a =  =
 = 
We require the hypotenuse h
Using Pythagoras' identity
h² = 9² + 40² = 81 + 1600 = 1681 ( take square root of both sides )
h =  = 41 , thus
 = 41 , thus
sin a =  =
 = 
cos a =  =
 =
