For this case we have that the sum of the interior angles of any polygon is given by the following expression:

(n-2) * 180

In this case it is observed that we have a figure with 6 sides. So:

n = 6

We replace:

(6-2) * 180 = 720

Thus, the sum of the interior angles should be 720 degrees.

So:

B + 133 + 102 + 117 + 90 + 170 = 720\\B = 720-133-102-117-90-170\\B = 108

Thus, angle B is 108 degrees.

If f(x) = 7x- 3 and g(x) = x2 - 4x- 8, find (f+ 9%).
zavuch27 [327]

Answer:

option D

Step-by-step explanation:

f(x) = 7x- 3

g(x) = x2 - 4x- 8

we have

(f+g)(x)= 7x- 3 +x2 - 4x- 8

(f+g)(x)= x2+ 3x- 11
