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
sin a = 
= 
cos a = 
= 
I’m sorry I’m late but you multiply that n(x)=200 by x=300 and n(xuy)=400
