1/2 I guess I don't think you typed in the question correctly. Not trying to be mean.
19. 5x - 5 = 3x -9
2x = -4
x = -2

Answer:
The answer is 60
Step-by-step explanation:
Just trust me :)
Check the picture below.
recall the ambiguous SSA case, as the "12" side moves, it ends up with two supplementary angles on the base.
Y = -3x + b
Plug in points
4 = -3(-2) + b
4 = 6 + b, b = -2
Solution: y = -3x - 2
