Determine if the two triangles are congruent. if they are, state how you know.

congruent. ASA

Step-by-step explanation:

you already know that a side and an angle are congruent. and the angles where the triangles meet are vertical angles so they are congruent. thus ASA

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

answer: the answer is 127 degrees
