Atriangle has two sides that are 8cm and 13cm. what could be the length of the triangles third side

5 < x < 21

Step-by-step explanation:

The sum of the shorter sides is greater than the longest side.

If 13 is the longest side:

x + 8 > 13

x > 5

If x is the longest side:

8 + 13 > x

21 > x

Therefore, the third side is any number between 5 and 21.

answer: do you still need this?

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
