Which of these is a correct step in constructing an angle bisector?

use a straightedge to measure the bisected angles

use a compass to join the point where the arcs cross the vertex

use a compass to draw two equal arcs from the intersection points of a previous arc and the legs

use a straightedge to draw arcs which intersect at a point

answer;

the correct answer

just use google you beautiful person.

have a nice day < 3

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

you probably already have the answer but anyways it's b. 15.0
