angles in a triangle add up to 180

so x = 180 - ( 70 + 90 ) = 20

this is because the two other angles in the both of the identical triangles are 70 and 90

Which value is equivalent to: 1 1/2 divided by 4 1/2 x 1 1/3

Nostrana [21]

Answer:

The answer is 4/9

Step-by-step explanation:

Hi. Here's the work.

First turn everything into an improper fraction.

$1 \frac{1}{2}$ ÷ $4 \frac{1}{2} * 1 \frac{1}{3}$ = $\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$

To divide fractions we multiply by the flipped version of the fraction, or the reciprocal.

$\frac{3}{2}$ ÷ $\frac{9}{2} * \frac{4}{3}$ = $\frac{3}{2} *\frac{2}{9} *\frac{4}{3}$

Now we just multiply the fractions!

$\frac{3 * 2 * 4}{2 * 9 * 3}$ = $\frac{4}{9}$

The answer is therefore 4/9. Please mark brainliest if possible and i hope you get a good grade on your homework. ;)

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:

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