Find the values of angles x y and z. me asap i have to have this done in 30 : ( you so

last one in list

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles in the left triangle from 180, that is

x = 180° - (23 + 75)° = 180° = 98° = 82°

Angles x and y form a straight angle, thus they sum to 180

y = 180° - x = 180° - 82° = 98°

Using the sum of angles on the triangle in the right

z = 180° - (54 + 98)° = 180° - 152° = 28°

Hence

x = 82°, y = 98°, z = 28°

true

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
