-16 + 9 = -7
Answer:
x = 77, y = 63
Step-by-step explanation:
x - 5 = 72 ( corresponding angles )
x = 77
The 3 angles on the straight line sum to 180°, that is
x - 5 + 51 + y - 6 = 180, that is
72 + 51 + y - 6 = 180
117 + y = 180 ( subtract 117 from both sides )
y = 63
Answer:
26cm
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
=

So the perimeter of ABC is half of the perimeter of DEF .
perimeter of DEF =
