You can use the triangle congruence theorem here because the hypotenuse and the leg of the two right triangles align.
Answer:
Step-by-step explanation:
number of side = n =7
Sum of all the angles of given polygon = (n -2)*180 = 5 *180 = 900
x + 140 +133 +145 + 117 + 119 + 125 = 900
x + 779 = 900
x = 900 - 779
x = 121
Vbox-vspheres
vbox=, I assume we are dealing with l=w=h
so
v=lwh=12^3=1728
vsphere=(4/3)pir^3
r=3
vsphere=(4/3)pi3^3=4pi9=36pi
8 of them so
8 times 36pi=288pi or about 904.7786842338604526772412943845 cubic inches
vbox-sphere=1728-904.7786842338604526772412943845=823.2213157661395473227587056155
space filled by packing beads is about 823.22 cubic inches
beads percent is 823.2213157661395473227587056155/1728 times 100=47.64% filled by beads
The digit in ones place is "2"
1.09 +
1.38
First, add the numbers in the hundredths column:
9+8=16
Carry the one, and add the numbers in the tenths column:
1+0+3=4
Now, add the numbers in the ones column:
1+1=2
Bring the decimal straight down.
The answer is 2.46
Hope this helps!!
