b×h=a
this is how to represent it and it is a direct variation.
3.20 divieded my 2 =1.6 spring 3.20 +1.6 =4.8
Vertical angles are equal and supplementary angles add to 180 degrees
Simply add and multiply the numbers and you get 13.235
in word form that would be
13 and 2 tenths and 3 hundredths and 5 thousandths
$62.35 because 40*12=480 480 divided by 7.65=62.35 or just 62
I hope this helps:)
