Answer:

28

Step-by-step explanation:

Since, Sum of triangle is equal to 180°

180 = 2x + 50 + 3x - 10

180 = 5x + 40

180 - 40 = 5x

140 = 5x

140/5 = x

28 = x

kap26 [50]

Synthetic division yields

..... || 2 2 -12 1 6

-3 || -6 12 0 -3

= = = = = = = = = = = = = =

..... || 2 -4 0 1 3

which translates to

$\dfrac{2x^4+2x^3-12x^2+x+6}{x+3}=2x^3-4x^2+1+\dfrac3{x+3}$
