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

ioda

Answer: SSS Similarity Theorem

Step-by-step explanation:

SSS Similarity Theorem says that the lengths of the corresponding sides of two triangles are proportional, then the triangles must be similar.

In the given picture , we have two triangles XYZ and KMN, where

$\dfrac{3}{4.5}=\dfrac{4}{6}=\dfrac{2}{3}$

$\Rightarrow\ \dfrac{XZ}{KN}=\dfrac{ZY}{MN}=\dfrac{XY}{KM}=\dfrac{2}{3}$

By SSS similarity theorem , we have

ΔXYZ ≅ ΔKMN

Suppose a horse is galloping at 19 mph toward a clown, and the clown is racing toward the horse on an ATV which can sustain a sp

egoroff_w [7]

Answer:

It will take 1.47 hours for the horse and clown to collide

Step-by-step explanation:

They are driving toward each other, in opposite directions.

So to find their speed of approximation, we add their speeds.

19 mph + 15 mph = 34 mph.

This means that each hour, they are 34 miles closer.

How long it takes for them to find each other if they are 50 miles apart?

1 hour - 34 miles

x hours - 50 miles

$34x = 50$

$x = \frac{50}{34}$

$x = 1.47$

It will take 1.47 hours for the horse and clown to collide
