Question

the lengths of two sides of a triangle are 20 cm and 15 cm respectively. show that the length of the third side will lie between 5cm and 35cm. ​

Answer 1

Answer:

third side of triangle lies between 35 cm. and 5 cm

Step-by-step explanation:

As we know that,

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

Length of two sides of a triangle are 20 cm. and 15 cm.

So the possible length of third side = 20 + 15 =35 cm.

And ,also the third side is greater than the difference of the two sides.

∴ Third side must be greater than 20 - 15 = 5 cm.

∴ 5 cm.< third side <35 cm.

Answer 2

Answer:

The length of the third side will lie between 5 cm and 35 cm.

Step-by-step explanation: Since we have given that

Length of two sides of a triangle are 20 cm and 15 cm.

Since we know that

Sum of two sides are always greater than the third sides.

So, possibility of length of third side would be

20+15=35 cm

20-15 = 5 cm

Hence, the length of the third side will lie between 5 cm and 35 cm.
