Answer:
A solution to a system of equations means the point must work in both equations in the system. So, we test the point in both equations. It must be a solution for both to be a solution to the system. Hope this helps.

Answer:
21.62m
Step-by-step explanation:
first draw the the pipe 
second you need know wich is the angle between the pipe and the corner
β=Tan^-1(6/9)=33.7
find the components using tow triangles
a=9/cos(33.7)=10.81m
b=6/sen(33.7)=10.81m
finally sum the leghts
L=10.81+10.81=21.62mm
attached procedure
 
        
             
        
        
        
Answer:
   cos(θ) = (√33)/7
Step-by-step explanation:
The relevant relation is ...
   cos(θ) = √(1 -sin²(θ))
   cos(θ) = √(1 -(4/7)²) = √(1 -16/49) = √(33/49)
   cos(θ) = (√33)/7
