Explain how to estimate the sum of the distances ran in

the three months to the nearest kilometer.

total distance andrea ran (kilometers)

march

april

may

48.7

31.2

35.66

The estimated sum of the distances ran in  the three months to the nearest kilometer is 116.

Step-by-step explanation:

Consider the provided Table.

Months     Total Distance Andrea Ran

March                     48.7  kilometers

 April                      31.2  kilometers

May                        35.66 kilometers

First round up the number to the nearest ones place as shown:

Months     Total Distance Andrea Ran

March                  48.7  ≈ 49 kilometers

 April                   31.2  ≈ 31 kilometers

May                     35.66 ≈ 36 kilometers

Now add them

49+31+36=116 kilometers

Hence, the estimated sum of the distances ran in  the three months to the nearest kilometer is 116.

∠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.
