Matrix :

1    4    4

5    2    2

1    5    5

=> Determinant =

1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)

= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0

Prove that < AOD and < BOD are supplementary
Karolina [17]

Angle AOD and < BOD are supplementary since they are both right angles which equal 180°.

<h3>What is a supplementary angle?</h3>

It should be noted that a supplementary angle simply means an angle that adds up to 180°.

In this case, the angles given are both rights angles. This will be:

= 90° + 90°

= 180°

In this case, Angle AOD and < BOD are supplementary since they are both rights angles which equal 180°.
