Answer: 9
Step-by-step explanation:
The interior angle of the 8-sided polygon is
![\frac{180(8-2)}{8}=135^{\circ}](https://tex.z-dn.net/?f=%5Cfrac%7B180%288-2%29%7D%7B8%7D%3D135%5E%7B%5Ccirc%7D)
The interior angle of the 10-sided polygon is
![\frac{180(10-2)}{10}=144^{\circ}](https://tex.z-dn.net/?f=%5Cfrac%7B180%2810-2%29%7D%7B10%7D%3D144%5E%7B%5Ccirc%7D)
Taking the difference, we get ![b=9^{\circ}](https://tex.z-dn.net/?f=b%3D9%5E%7B%5Ccirc%7D)
Answer:
-15
Step-by-step explanation:
Multiply: (-3)8= -24
Add: -4+6+3+1+0+2+1= 9
Subtract: 9-24= -15
