Given the diagram classify the bolded line as a perpendicular bisect or angle bisect or median or altitude write your answer on the line

altitude

Step-by-step explanation:

It cant be a perpendicular bisector because its not splitting the triangle into equal lengths.

its 69.420

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option
