For the following four exercises, determine the type of sampling used (simple random, stratified, systematic, cluster, or convenience). 12. A group of test subjects is divided into twelve groups; then four of the groups are chosen at random. 13. A market researcher polls every tenth person who walks into a store. 14. The first 50 people who walk into a sporting event are polled on their television preferences. 15. A computer generates 100 random numbers, and 100 people whose names correspond with the numbers on the list are chosen.

∠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.
