These triangles ARE similar! Which reason proves it?
andrew-mc [135]

Answer:

SAS

Step-by-step explanation:

From the image attached below, in triangle ABC, AB = 15, AC = 20 while in triangle ADE, AD = 12 and AE = 16

Two triangles are said to be similar if they have the same shape, that is either their corresponding angles are the same or their corresponding sides are proportional.

For both triangle ABC and triangle ADE, they have the same angle which is ∠A. Also:

\frac{AD}{AB}=\frac{12}{15}=\frac{4}{5}

\frac{AE}{AC}=\frac{16}{20}=\frac{4}{5}

Since two sides of triangle ABC are in the same proportion as two sides of triangle ADE and they have the same angle, therefore they are similar based on the SAS  (side-angle-side) similarity

Michael ran 655 feet in 19 seconds jasmine ran 1 mile in 4 minutes and 24 seconds in miles per hour and to the nearest tenth how
Natalka [10]

Answer:

<h2>25 mph</h2>

Step-by-step explanation:

<h3>Step 1: Convert miles to feet</h3>

First, we need to convert the miles to feet keeping in mind that:

1 mile = 5,280 feet

655 ft 19 sec

5,280 ft 4 min 24 sec

<h3>Step 2: Divide the distance by the time to find the unit rate</h3>

3,447 feet per minute

1,245 feet per minute

<h3>Step 3: Convert minutes to hours</h3>

206,820 feet per hour

74,700 feet per hour

<h3>Step 4: Convert feet to miles</h3>

39.17 miles per hour

14.15 miles per hour

To find how much faster Michael ran, we need one more step.

<h3>Step 5: Subtract smaller amount from larger amount</h3>

39.17 - 14.15 = 25

I'm always happy to help :)
