Answer:
x= 80
Step-by-step explanation:
70 +30=180
sum of angles is triangle is 180 degree
sp 180-100= 80
The factor theorem states that if (x-a) is a factor of P(x) the P(a) = 0 so we can write, for this polynomial:
2^(4) - 3(2)^3 + A(2)^2 - 6(2) + 14 = 0
16 - 24 + 4A - 12 + 14 = 0
4A = -16+24 + 12 - 14 = 6
A = 6/4 = 1.5
