Answer:
Volume of Cube = length cube
Total surface area=2(lb+lh+bh)
Volume of Cuboid=l×b×h
I think it will help you.
Step-by-step explanation:
midpoint : it is the point in the middle marking half of the total distance.
therefore,
1)
EV = LE = LV/2
10 = 5m
m = 2
2)
LR = RO = LO/2
n + 4 = 12
n = 8
3)
LER and LVO are similar triangles. that means they have the same angles, and the ratio of one corresponding pair of lines or sides between both triangles is the same for all corresponding line pairs.
we know e.g. LE/LV = 1/2.
the same ratio applies then to ER/VO = 1/2 = 18/20p.
18/20p = 1/2
18 = 20p/2
2×18 = 20p
36 = 20p
p = 36/20 = 9/5 = 1.88888888888...
4)
VL = 2×EL = 2×10 = 20
5)
LO = 2×RO = 2×12 = 24
6)
as we have already calculated for 3) :
VO = 36
7)
36 + 20 + 24 = 80
8)
10 + 12 + 18 = 40
9)
remember, the and angles in similar triangles.
LVO = 52°
10)
all angles around a single point in one side of a line are together 180°.
in this case there are 2 angles around E : LER and VER.
VER = 180 - LER = 180 - 52 = 128°
Answer:
i'm pretty sure the answer is -
BC = 8.1
Step-by-step explanation:
First off,congruent triangles are triangles that are equal to another,having the same area,length of sides and angles.
Judging visually,the triangles that are congruent would be:
C and E-as they are both in smaller size.
D and F-as they are both significantly irregular.
That would left A and B:
A-it is very large in size that none other could match
B-it is the only isosceles triangle.
Thus the answer is A and B as they do not match with any others.
Hope it helps!
