Answer:
1/81
Step-by-step explanation:
Since area is length times width, it would be the factors of the equation for the area.
X2+11x+28 factors into...
Length is x+7 so...
Width is x+4
I hope you meant find x
5x + 3x + 2x = 180. x=18
If its a triangle u have to add the given angles and subtract by 180 to get x
