It is a geometric sequence where you have to find the ratio miltiply only and the sequence is 9,-3,1,-1/3

The common ratio to the given geometric sequence is

Therefore common ratio is

Step-by-step explanation:

Given sequence is 9,-3,1,

Given that the given sequence is a geometric sequence

To find the common ratio of the given sequence :

Let

Common ratio

Substitute

Therefore

Common ratio

Substitute

Therefore

The common ratio to the given geometric sequence is

Therefore common ratio is

answer:

step-by-step explanation:

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

step-by-step explanation:

given   that triangle lno is congruent to triangle lnm.

we have to fill up the blanks in the given question.

according to above order of congruency   kept in mind we can say that

∠lno ≅ ∠lnm

∠oln ≅ ∠mln

ln ≅ ln due to common in both.

hence, by sas congruency,

the side angle side rule   states that if two sides and the included angle of one triangle are congruent to another triangle, then these two triangles are congruent.
