Question

6. The lengths of two sides of a triangle are 12 cm and 15 cm. Between what two
measures should the length of the third side fall? please please please help me​

Answer 1

Answer:

Let AB,BC and CA are the sides of triangle ABC

Let AB,BC and CA are the sides of triangle ABCGiven that,

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know that

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BC

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.And

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.AndCA=AB+BC

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.AndCA=AB+BCCA=15+12

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.AndCA=AB+BCCA=15+12CA=27cm.

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.AndCA=AB+BCCA=15+12CA=27cm.So the third side CA must lie between 3<CA<27cm.

Let AB,BC and CA are the sides of triangle ABCGiven that,Let AB=15cm,BC=12cm and Third side CA=?Then, We know thatCA=AB−BCCA=15−12CA=3cm.AndCA=AB+BCCA=15+12CA=27cm.So the third side CA must lie between 3<CA<27cm.Hence, this is the answer.
