Bob has scores of 72, 95 and 80 on his first three test what score does he need to get on his for test to have an average of at least an 85

He has to get 93 score in the fourth test.

He scored 72, 95 and 80 in the 1st three tests.The summation of the scores become (73+95+80)=247.

Now to get an average of 85 ,he has to score a total of (85×4)=340 score.

So in the last test the score needed for him to get an overall average of 85 is 340–247=93.

Step-by-step explanation:

∠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.
