Paul pays R3 000 into an eight-year savings account at the end of each month starting three months after his decision to start saving. The interest is
18% per annum compounded monthly. If the investment period, starting
from his decision to start saving, is eight years, calculate the future value of
the investment at the end of the eighth year.

∠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.

i think it might be a but you might want a second opinion
