Answer:
Step-by-step explanation:
"The octagon has 8 sides and we plug this value into our formula: S = 180(8 - 2) = 1080°. the sum of the measures of the interior angles in an octagon is 1080°. " i found this from google.
9. I think Austin has more rainfall.
10. Both cities have unguessable rainfalls.
11. I predict the rainfall will continue going high, then low, then high, then low.
Since abc is congruent to def a and d are congruent angles
So you can set the equation to x + 39 = 2x
Solve to get x = 39
Plug that into (x + 39)
You should get a= 78 degrees
Since a and d are congruent, d is also equal to 78 degrees
A because if you take the 190000 and multiply it by 3% and then subtract which is 5700 and take 190000 and subtract it by 5700 it will give u the answer is 184300
Step-by-step explanation:
2x+1=9
2x=9-1
2x=8
x=8÷2
x=4
