Find the reduced row echelon form of the augmented matrix

Top row: [1 0 0 | 650}

Middle row: [0 1 0 | -400]

Bottom row: [0 0 1 | -1100]

Step-by-step explanation:

When you put an augmented matrix in RREF for, you have to have only 1's diagonal and 0's everywhere else on the left side of the bar.

sas (side angle side)

aa(angle angle)

sss(side side side)

sas you have to find two sides with an angle in between

aa you find two angles because it will always add up to 180

sss find all sides

step-by-step explanation:

part a: 1.08

part b: 27.59
