Two angles of a triangle measure fifty degrees and forty degrees. What does the third angle measure? Need ans ASAP giving u 15points

The answer is 90 degrees

third angle is 90 degree

Step-by-step explanation:

one angle is 50 degree

another angle is 40 degree

third angle = ?

let third angle be x

50 + 40 + x =180 degree (sum of interior angles of a trianglle)

90 + x =180

x = 180 - 90

x = 90 degree

(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
