A library has 300 feet of shelves for books. The library will increase the number of feet of shelves by 18%.
A How many feet of shelves are being added?

54

Step-by-step explanation:

Well, divide 300 by 100, which gets you 3. So 3 feet of book shelves = 1%

So 3x18=54

∠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.
