Answer:
here is your answer...
Some relationships:
Angle FGH + Angle FHG = 90
sin(FGH) = cos(FHG)
cos(FGH) = sin(FHG)
Idont know that question
The first equation will turn into -18x -6y = -18, and the second equation will turn into 14x + 6y = 18. The y terms will cancel out when you add the equations together.
