Sum of angles in a triangle is 180 degrees.
2x + 2x + 8x = 180
12x = 180
x = 180/12 = 15
Therefore, the smallest angle mmeasures 2(15) = 30 degrees.
<span>For each one . . .
=> solve the
equation for 'y'. That means massage it around until it's
in the form
of <em> y</em> = (thing1) <em>x</em> + (thing2).
=> When you do that, then 'thing1'
is the slope of the line on the graph,
and 'thing2' is the number
where the line crosses the y-axis.
=> When you have those two
numbers, drawing the line on the graph
is a piece-o-cake.</span>
Answer:
c) -6
Step-by-step explanation:
50 + 90 + (x+46) = 180 (angle sum property)
186 + x = 180
x = 180 - 186 = -6
I hope im right!!
I hope this helps you
f (x)=x^2 (x^2-1)
f (x)=x^2 (x-1)(x+1)
