Answer:

D. 18

Step-by-step explanation:

The polygon given is a 5-sided polygon (pentagon). Sum of all interior angles of a 5-sided polygon = (n - 2) * 180°

= (5 - 2) * 180 = 540°

Therefore:

95° + (7x - 4)° + (3x + 23)° + (9x - 6)° + 90° = 540°

Solve for x

95 + 7x - 4 + 3x + 23 + 9x - 6 + 90 = 540

Add like terms

198 + 19x = 540

19x = 540 - 198

19x = 342

x = 342/19

x = 18

Perform the indicated operation and simplify the result.

harina [27]

$\frac{b^{2}-3b-10 }{(b-2)^{2} }$ · $\frac{b-2}{b-5}$ =

$\frac{(b-5)(b+2)}{(b-2)^{2} }$ · $\frac{b-2}{b-5}$ =

$\frac{(b+2)}{(b-2) }$ · $\frac{1}{1}$ = (semplify)

result = $\frac{(b+2)}{(b-2) }$
