What is the sum of the first 47 terms of the sequence
-215,-201.-187.-

-208 bc it’s the right one I swear

I believe the answer would be 443. I came up with my own way of solving it without going through the long process. Since the pattern is 14 gets added onto each number, I decided to multiply 14 x 47 = 658. Then I added 658 + (-215) and got 443. This is NOT how it should be done, but I if I am wrong, let me know and I'll redo the calculation(s).

∠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.
