832
Step-by-step explanation:
If you have one group of 832, and put it into 1 group you get 832
It depends, not exactly, because the techtonic plates aren't connected.
Answer:
It's -3 mate
Step-by-step explanation:
I just did the test
Supplementary angles add to 180
4+5=9
180/9=20
4*20=80
5*20=100
the angles are 80 degrees and 100 degrees
The 9-sided polygon will have a central angle between the vertex and the center of one side of 360°/(2*9) = 20°. Then the apothem is
a = (6 in/2)*cot(20°) ≈ 8.242432 in
The perimeter is 9*6 in = 54 in, so the area is
A = (1/2)Pa = (1/2)*(54 in)*(8.242432 in) ≈ 222.5 in²
