I have attached a photo of the work written for this question:
62+92 is 154. 180- 154 is 26
Two lines are "inconsistent" if they are parallel. They are "equivalent" if they are the same line. Otherwise, they are "consistent."
Your first 3 graphs show "consistent" equations.
The 4th graph shows "inconsistent" equations.
The solution shown on the 5th graph is where the lines intersect, near point
(5, 3)
5x + 2x + 3x = 180
10x = 180
x = 18
Angles are 36, 54, 90
It is called a "carrot" in most teachers math vocabulary, Type in your base, then click the ^ button, then type in your exponent.
