Answer:
22.5 degrees
Step-by-step explanation:
there are 8 corners in that polygon and there are 180 degrees inside every polygon
so divide 180 by 8
you should get 22.5 degrees
If B^2 then
9^2 = 81
answer
b. 81
----------------------------------
if If B2 then
9*2 = 18
answer
a. 18
------------------
Two tailed ..? Lol I haven’t learned this yet but I am taking a guess what two tailed
2x - 9x = 14 (Careful next time you accidentally added an "equal" next to the 2)
-------------------------------------
Simplify
2x-9x=<span>14
</span><span>2x+-9x</span>=<span>14
</span>--------------------------------------------
Combine the like-terms
<span>(<span>2x+-9x</span>)</span>=<span>14
</span><span><span>-7x</span></span>=<span>14
</span>--------------------------------------------------
Now divide -7 to each side
-7x ÷ -7 = 14 ÷ -7
x = -2
------------------------------------------------------
x = -2 is your answer
