Triangle abc (a- 12cm b- 6cm) is similar to ayz, whats the value of x

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 =

answer 26 cm.

last one.

step-by-step explanation:

last one.

generally speaking, the others follow some sort of pattern that correlates to either linear (looks like a straight line) or sinusoidal (looks like an s).

the last one is just a random cloud of points that doesn't correlate to any particular known order.

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
