I need help ASAP please ;-; are the two triangles similar (yes or no) and are the congruent (yes or no) btw what’s is x=?

I only know the answer to part A. The triangles ARE similar and they ARE congruent.

Step-by-step explanation:

The big triangle has 75° and 60°.

The little triangle has 75° and 45°

75°+60°+45° = 180°

45° is the missing interior angle for the big triangle.

75°+45°+60° = 180°

60° is the missing interior angle for the little triangle.

step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0
