Can someone me on this question and explain how you got the answers

540

Step-by-step explanation:

The sum of the measures of the interior angles of a polygon with n sides :

(n – 2)180

As you know, pentagon has 5 sides so n = 5

Sum of the interior angles of a pentagon

= (5 - 2) 180

= (3) 180

= 540

∠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.
