I believe in Vertex form it would be (-5,-4)
Simple Proof:
a) In the image, we know that ABCD is a parallelogram and that means opposite angel measures should be the same. We know that angel DCB is made up by angel 1 and 2, and angel DAB and DCB are equal and angel DAB is made up by angel 1 and <em>x</em>. So now we can conclude that angel <em>x</em> is equal to angel 2.
b) According to the definitions of a parallelogram, opposite angel measures have to be the same, while AECF have angle 1 to angel 1 and angel 2 to angel 1. We can conclude that AECF is <u>NOT</u> a parallelogram. (Sorry, you didn't give me the full question so some information remains unclear. )
Answer:
9p = 81 degrees
Step-by-step explanation:
All the angles in a triangle equal 180 degrees in total.
So the equation would be:
9p + 7p + 4p = 180
20p = 180
p = 9
So just plug it in:
9(9) 7(9) 4(9)
81 degrees 63 degrees 36 degrees
