18 cm, 6 cm, 12 cm

Answer 1

@TheSmartOne @Nnesha could you guys help me please? I think the answer would 18 cm, 6 cm, 12 cm.

Answer 2

The sum of the lengths of any two sides of a triangle is greater than the length of the third side. If you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side.

Answer 4

no its b. since 15, 8<22<15+8

Answer 5

a can be too i think.

Answer 6

Thank you so much for the link @TheSmartOne so would the answer be C?

Answer 7

13+8=?
And is it greater than 22?

Answer 8

its b or A i dont think its c

Answer 9

on a 12+ 6 equals 18 and that is not greater than18 so it can't be a
and c 13+18=21 which is smaller than 22

Answer 10

13 + 8 = 21, It's smaller than 22.

Answer 11

So C is not correct

Answer 12

22 + 8 = 30, 30 is bigger than 22.

Answer 13

So would it be B?

Answer 14

when you add two sides that should be greater than of 3 side example
like this
