Answer:
i think c
Step-by-step explanation:
The one that does not belong is plane CDE, the reason being the rest are line segments. Line segments differ from the planes because they have fewer number of dimensions as compared to the planes. Thus the correct answer is:
plane CDE
reason being:
The one that does not belong has different number of dimensions
So we are given two points, say P1(4,7), P2(x,19).
Slope is given by
m=3=(y2-y1)/(x2-x1)=(19-7)/(x-4)
solve for x
3=(19-7)/(x-4)
cross multiply
3(x-4)=12
3x-12=12
3x=12+12=24
x=8
Answer:
none of them
Step-by-step explanation:
The area (A) of a triangle is calculated as
A = 0.5 × base × perpendicular height
Here the base is BC and perpendicular height is AD, hence
Area of ΔABC = 0.5 × BC × AD
