Question

If two sides of a triangle are 8cm, 11cm, then the possible length of the thrid side is​

Answer 1

answer

161

Step-by-step explanation:

all sides of traingle is 180

let the third side be ×

one side is 8cm

another is 11cm

8cm+ 11cm + × =180

19cm + × = 180

×= 180- 19

161

third side = 161

Answer 2

since,the sum of lengths of any two sides in a triangle should be greater than the length of the third side.

it is given that two sides of triangle are 12cm and 15cm.

therefore, the third side should be less than

12+15=27cm

and also the third side cannot be less than the difference of the two sides.

therefore,the third side has to be more than

15-12=3cm

therefore,the third side should be length more than the 3cm and less than 27cm.

therefore, 3cm< 3rd side < 27cm
