Graph A because the slope and y intercept is correct on that graph
<span>The sum of the interior angles of a triangle is 180 degrees
</span>
4x + 5x + 6x = 180
15x = 180
x = 180/15
x = 12
<span>The measure of the smallest angle = 4x = 4*12 = 48</span>°
(-6)*(-6)*(-6)=-216.
Therefore, the cubed root of -216 is -6.
