The first term in a geometric series is 64 and the common ratio is 0.75.
Find the sum of the first 4 terms in the series.

175

Step-by-step explanation:

64,48,36,27

mulitply the term before by the ratio

64+48+36+27=175

∠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.
