Answer:

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

Step-by-step explanation:

You can use these Cramer's formulas to solve for x and y:

$x=\dfrac{|A_x|}{|A|},\\ \\y=\dfrac{|A_y|}{|A|},$

where

$|A|=\left|\begin{array}{cc}12&-13\\ \\17&-22\end{array}\right|\\ \\ \\|A_x|=\left|\begin{array}{cc}7&-13\\ \\-51&-22\end{array}\right|\\ \\ \\|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

So,

$|A_y|=\left|\begin{array}{cc}12&7\\ \\17&-51\end{array}\right|$

What is the value of x in the diagram below?

Tanzania [10]

Answer:

The answer to your question is: x = 100

Step-by-step explanation:

It's a polygon of 7 sides

The sum of internal angles in a polygon equals 180(n-2), where n = # of sides

Internal angles = 180(7-2)

= 180(5)

= 900°

(x + 50) + (x + 50) + (x + 50) + x + x + x + (x + 50) = 900

4(x + 50) + 3x = 900

4x + 200 + 3x = 900

7x = 900 - 200

7x = 700

x = 700 / 7

x = 100
