Just do 12 times 2 d=24 because 24 divided by 12 =2
Answer:
x=13
Step-by-step explanation:
We add all the numbers together, and all the variables
6x-78
We move all terms containing x to the left, and all other terms to the right
6x=78
x=78/6
which should equal 13
Your answer should be 1.7
I hope this helps! Good Luck!
So the ratios are 4 to 5 to 5 to 8 to 9 to 9
that means that the first 2 sides can be simplified to 4 to 5
therefor the whle sum is all the units added up
4+5+5+8+9+9=40
720=40 units
divide by 40
18=1 unit
solve for each unit
we have
4 units
5 units
8 units
9 units
4 times 18=72
5 times 18=90
8 times 18=144
9 times 18=152
the angles are
72,90,90,144,152,152
