X < z + y

we have to get x by itself so we need to get rid of the -y. add y to both sides. -y and +y cancel each other out on the left side

Graph the image of kite ABCD after a rotation 180° counterclockwise around the origin.

rewona [7]

Solution:

Given a kite ABCD on a graphhh, with the coordinates given below

$\begin{gathered} A(-8,-6) \\ B(-7,-2) \\ C(-1,-6) \\ D(-7,-10) \end{gathered}$

If the kite is rotated 180° counterclockwise around the origin,

The rule for a rotation 180° counterclockwise around the origin is

$(x,y)\rightarrow(-x,-y)$

The coordinates of the kite after the rotation of 180° counterclockwise around the origin will be

$\begin{gathered} A(-8,-6)\rightarrow A^{\prime}(8,6) \\ B^{\prime}(-7,-2)\rightarrow B^{\prime}^(7,2) \\ C(-1,-6)\rightarrow C^{\prime}(1,6) \\ D(-7,-10)\rightarrow D^{\prime}(7,10) \end{gathered}$

The graph is shown below

Help how can I solve for b?

Viefleur [7K]

Answer:

93 degrees

Step-by-step explanation:

You would add 23 to 244 and get the total of 267 which is the two other angles. A whole circle is 360 degrees so you would subtract 267 from 360 and get 93 degrees.
