Arandom draw is being designed for 210 participants. a single winner is to be chosen, and all the participants must have an equal probability of winning. if the winner is to be drawn using 10 balls numbered 0 through 9, a minimum of how many balls need to be picked, regardless of order, so that each of the 210 participants can be assigned a unique set of numbers?

Its 4

Step-by-step explanation: I just did test

∠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.
