Help Idk what I did wrong show your work please

x = 10

Step-by-step explanation:

first Add 20 to both sides.

4x = x + 10 + 20

Then Simplify x + 10 + 20 to x + 30

4x = x + 30

Then u subtract x from both sides

4x - x = 30

Simplify 4x - x to 3x

3x = 30

Then u divide both sides by three

x = 30/3

Then u last simplify 30/3 to 10

x = 10

∠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.

answer: i guess 105 degrees?
