Answer: x=5, y=-5, z=6
Step-by-step explanation:
x+y+z=6 -> 2x+2y+2z=12
subtract 2x+4y+2z=2 from this, and you get -2y=10 -> y=-5
So, x+z=11 and -x-3z=-23
x+z=11
-x-3z=23
---------
-2z=-12
z=-6
Meaning x=5.
Answer:
x = 45°, y= 5°
Step-by-step explanation:
x = 9y

2x = 90
x = 45
so x = 45
9y = 45
y = 5
