16. 15 = –11b + 4 what is b

b=-1

Step-by-step explanation:

First you have 15= -11b +4

You want to subtract 4 from both sides, so on the left side you get 11 and on the right side you only have -11b because 4-4 cancels out and gets you 0.

11=-11b

Then divide both sides by -11 and the right side equals b and the left side equals -1. So, b = -1.

∠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.

it would rotate about 180 degrees.
