<h2>Answer:</h2>

The correct choice among the given choices is:

Option: a

a. 180° ; 90°

<h2>Step-by-step explanation:</h2>

Supplementary angles are two angles whose measures have a sum of 180 degree.

( for example the two angles adjacent to each other on a straight line are supplementary )

Complementary angles are two angles whose measures have a sum of 90 degrees.

( For example--

The diagonal of a square divides the angle into two parts such that both the angles sum up to 90 degrees.

Hence, the two angles are complementary )

Point A has coordinates (6,4) and point B has coordinates (2,7) write AB as column vector. Plz plz plz

Olenka [21]

Answer:

$\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}$

Step-by-step explanation:

<u>Column Vector</u>

Vectors are matrices having only one column or one row. A vector having only one column is called a column vector, and a vector having only one row is called a row vector.

It's required to find the vector AB as a column vector, and we are given the coordinates of A=(6,4) and B=(2,7).

The vector directed from A to B is found by subtracting its corresponding coordinates:

$\overrightarrow{AB }=$

Now we express the vector as a one-column matrix as follows:

$\overrightarrow{AB }=\begin{bmatrix}-4\\3 \end{bmatrix}$
