El Dr. Potter aplicó 32 vacunas de polio y 28 de sarampión.

Step-by-step explanation:

- First, the data must be taken into account to create the equations:

- Where:

 X = Number of polio vaccines and Y = Number of measles vaccines.

Where for each polio vaccine there are 4 doses and for each measles vaccine there are 2 doses.

- We clear the variable that we want to find in each equation:

- Now both equations are equalized in terms of the same variable:

- Then X is cleared to find its value:

- Now we demonstrate the value of X obtained in equation 1 or 2 to give the values of Y

- Finally, both values are used to see if equation 2 gives us the correct data:

- The answer is given:

Dr. Potter gave 32 polio and 28 measles vaccines.

∠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.
