the inverse of a two-by-two matrix
A=
whose inverse is
Substituting values, we get
which is not the same as matrix B. Therefore B is not the inverse of A.
We can prove similarly that A is not the inverse of B.

Answer:
x = 10
y= 12
Step-by-step explanation:
We know that TSV = 90 degrees
5x+4x = 90
9x = 90
Divide by 9
9x/9 = 90/9
x = 10
We know that RSU = 180
10y+10 +5x= 180
10y + 10 + 5(10) = 180
10y + 10 +50 = 180
10y +60 = 180
Subtract 60 from each side
10y = 120
Divide by 10
y = 12
