The four color theorem-No more than 4 colors are required to color the regions map
Step-by-step explanation:
7x+5y=25 ×3 7×-1.5+5y=25
5x+3y= -23 ×5 -10.5 +5y =25
5y= 25 + 10.5
21x+15y=75 5y= 35.5
25x+15y=69 y= 7.1
-4x=6
x=-1.5

Hope this helps answer your question and have a nice day ahead.
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 =
=
