Step-by-step explanation: we want a triangle with shorter sides (smaller perimeter) and we got 2 similar triangles , since triangles are similar the corresponding sides would be in ratio.
To get triangle of shorter perimeter we have to use the longest side of
△
A
B
C
put 6cm side corresponding to 12cm side.
Let
△
A
B
C
~
△
D
E
F
6cm side corresponding to 12 cm side .
therefore,
A
B
D
E
=
B
C
E
F
=
C
A
F
D
=
1
2
So the perimeter of ABC is half of the perimeter of DEF .
perimeter of DEF =
2

(

+
6
)
=

answer 26 cm.
1) a = tickets in advance goal = 2000
d =tickets at door
6a +8d = 2000
6(142)+8d =2000
852+8d=2000
8d=2000-852
8d=1148
d=1148/8
d=143.5
round up d=144 need to sell 144 tickets at door
Supplementary angles are angles that when you add them, make 180 degrees, which is a straight line. They are not to be joined together but added. So if one measures 90 degrees more than another, well what's the answer? I hope this helps.
