Find the measure of anglexin the figure below:O 95O 55O
jolli1 [7]
Since a triangle equals 180°

We know that x and y angles are the same. 

And that 55° + 30° + y = 180°

We just subtract!
sooo
180 - 55 - 33 = 95 

So this means y = 95°

And x and y equal the same measurement. 
sooo you answer is...

<span>x = 95°

Describe two different sequences of transformations that will map ABCD to EFGH.
Harlamova29_29 [7]
The orientation of the figure has been changed by 90°, but the points are not all rotated around the same center. Translation is involved.

Translation before rotation:
.. translate down 5 units
.. rotate counterclockwise 90° about the origin

Translation after rotation:
.. rotate counterclockwise 90° about the origin
.. translate right 5 units


This can also be accomplished by a double reflection.
.. reflect across the line y=x
.. reflect across the line x=2.5

Or, 
.. reflect across the line y=2.5
.. reflect across the line y=x
