Given that np/nq=nm/nr, select the postulate or theorem that you can use to conclude that the triangles are similar? asa similarity postulate sas similarity theorem sss similarity theorem aa similarity postulate

given 2 sides are in same ratio plus a common angle, similarity is proven by SAS.

In this question, the ratio of corresponding sides are in same proportion. That is

Here the corresponding sides are NP , NQ and NM , NR and the included angle is angle N .

So the two triangles are similar by SAS and out of the 4 options, correct option is the second option .

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
