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
the horizontal tangent line mean y'=0
8 - 2x = 0
x = 4
What do they mean by describe the diagram
Answer:
4/10
Step-by-step explanation:
10-6=4 therefore it is 4/10
