Answer:
3 -1 -2
5 1 6
Step-by-step explanation:
An augmented system has the coefficients for the variables and then the solution going across
Rewriting the equations to get them in the form
ax + by = c
-3x+y =2
3x-y =-2
5x+y = 6
The matrix is
3 -1 -2
5 1 6
For 9: All the angle should add up to 360 degrees.
So 152+50=202
360-202=158 degrees (Missing angle measure)
Method being used: All angle should add up to 360 degrees.
