Answer:

b = 68°

Step-by-step explanation:

he's your solution

=> angle of a polygon is given by =

(2n -4)*90°

=>(2*8 - 4) *90°

=> 12*90°

=> sum of all angles = 1080°

=> now, 150°+144°+127°+2b+b+50°+2b+11°+2b-20°+2b+6° = 1080°

=> 9b + 468° = 1080°

=> 9b = 612°

=> b= 612°/9

=> 68°

hope it helps

Solve and show your work. 12-[2 + 6 ÷ (10 - 2³)]

Svet_ta [14]

Answer:

Step-by-step explanation:

$2^{3} = 8$
Plug 8 in: 12 - [2 + 6 ÷ (10 - 8)]
10 - 8 = 2
Plug 2 in: 12 - [2 + 6 ÷ (2)]
6 ÷ 2 = 3
Plug 3 in: 12 - [2 + 3]
2 + 3 = 5
Plug 5 in: 12 - 5
12 - 5 = 7

I hope this helps!
