If it is a rhombus then you know each side is the same length, so only have to work out one side. To do this you have to use Pythagoras' theorem (a^2 + b^2 = c^2)
So take two sets of coordinates, for example, (0,3) and (5,3), a and b represent the height difference and the length difference. Therefore (5-0)^2 + (3-3)^2 = c^2
c^2 = 25
c = 5 , which would be the side of the rhombus
138 because 92/4 equals 23 which is the miles per gallon, then you multiply that by 6<span />
45/14 = a product every 3 minutes and 21 seconds

Step-by-step explanation:
this will help you.
A and 90-a is the measure of the two angles
a=90-a-6
2a=84
a=42
42° and 48°
