Select the postulate or theorem that you can use to conclude that the triangles are similar.

insens350 [35]

Answer: SAS similarity postulate

Step-by-step explanation:

According to SAS postulate of similarity, two triangles are called similar if two sides in one triangle are in the same proportion to the corresponding sides in the other, and the included angle are congruent.

In triangles, QNR and MNP,

$\frac{QN}{MN} = \frac{QM+MN}{MN} = \frac{10+8}{8} = \frac{18}{8} = \frac{9}{4}$

$\frac{NR}{NP} = \frac{NP+NR}{NP} = \frac{10+8}{8} = \frac{18}{8} = \frac{9}{4}$

$\implies \frac{QN}{MN} = \frac{NR}{NP}$

Also,

$\angle QNR\cong \angle MNP$ (Reflexive)

Thus, By SAS similarity postulate,

$\triangle QNR\sim\triangle MNP$

⇒ Option first is correct.

How do I do #12? <br><br> Please show all work. <br><br> Please help!

You have the ratio set up correctly:

2x+2/12 = x+3/21

Now cross multiply:

2x+2 * 12 = x+3 * 21

Simplify:

24x + 24 = 21x + 63

Subtract 24 from each side:

24x = 21x + 39

Subtract 21x from each side:

3x = 39

Divide both sides by 3:

x = 39/3

x = 13
