Anyone? i need help asap plzzz i’ll mark you as brainlist and like it

x = 50°

Step-by-step explanation:

Recall that for a triangle, the exterior angle is equal to the sum of its two remove interior angles (also see attached for reference).

in our case, the exterior angle is given as 105° and its two remote interior angles are x and 55°

therefore

105° = 55° + x

x = 105° - 55°

x = 50°

B. 50°

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
