The sum of the interior angles of a triangle is 180 so to find x your equation would be (x+15)+(2x-20)+(2x)=180...once you solve this equation x should be 37...and now you just plug in 37 for x and solve for the angle measurments....(37+15)=52....(2(37)-20)=54....2(37)=74

Answer:
When writing an inequality from a graph, there are a few things we need to do:
Determine the equation of the line. This gives us the general form of our inequality once we remove the equal sign.
Note whether the line is dotted or solid. ...
Use the graph's shading to determine which way you
Multiplication...?? Because if u add a times sign between 4x and -4 then u get 4x
