Answer:
120°
Step-by-step explanation:
A line must add up to 180°.
The sum of angles in a triangle also adds up to 180°.
Step 1: Find measures interior angles.
3x = 180
x = 60°
Step 2: Find measures of exterior angels.
x + 60 = 180
x = 120°

Step-by-step explanation:
Calculate the distance d using the distance formula
d =
with (x₁, y₁ ) = ((- 2, - 3 ) and (x₂, y₂ ) = (x, 5x + 9 )
d =
=
=
They are intersecting at 0,0.
One square on that chart is 2 units.
You can see this since it goes -10 then skips one then goes to -6.
The one in between is -8.
On every side of the intersection there is a 2 or -2.
2 - 2 or -2 + 2, depending if it's positive or negative, is 0.
So the lines are intersecting at 0,0.
Hope this helps! :)

Answer:</h2><h2>The final thickness of the metal = 2 inches.</h2>
Step-by-step explanation:
Jonathan finds a piece of metal that is 2 inches thick.
The thickness of the metal = 2 =
He files off inch,
the thickness becomes = - =
He adds a protective covering to the metal that is inch thick.
the thickness becomes, + =
Then, he polishes the metal and removes an additional inch.
The final thickness becomes, - = 2 inches
