If ∠BAC = 17° and ∠CED = 17° are the two triangles, ΔBAC and ΔCED similar? If so, by what criterion?
Alborosie

No, not possible to tell that the the two triangles, ΔBAC and ΔCED

are similar ⇒ answer D

Step-by-step explanation:

Let us revise the cases of similarity

1. AAA similarity : two triangles are similar if all three angles in the first

  triangle equal the corresponding angle in the second triangle  

2. AA similarity : If two angles of one triangle are equal to the

   corresponding angles of the other triangle, then the two triangles  

   are similar.

3. SSS similarity : If the corresponding sides of the two triangles are

   proportional, then the two triangles are similar.

4. SAS similarity : In two triangles, if two sets of corresponding sides  

   are proportional and the included angles are equal then the two  

   triangles are similar.

In the two triangles BAC and CED

∵ m∠BAC = 17°

∵ m∠CED = 17°

∴ m∠BAC = m∠CED

But we need another pair of angles to prove that the two triangles are

similar by AA similarity criterion

<em>OR </em>

The lengths of sides BA , CA and CE , DE to show that

\frac{BA}{CE}=\frac{CA}{DE} = constant ratio and prove that the

two triangles are similar by SAS similarity criterion

So it is not possible to prove that the two triangles are similar

No, not possible to tell that the the two triangles, ΔBAC and ΔCED

are similar

How do you write 6,301.005 in standard form
Orlov [11]
<h3>Answer:</h3>

One of ...

  • 6,301.005
  • 6.301005×10³
<h3>Step-by-step explanation:</h3>

It depends on where you are.

In the US, standard form is the way you have written the number. Your number would be 6,301.005.

The attachment gives some guidance for number formats in American publications. In certain publications, thin spaces are used instead of commas to separate groups of digits. The comma (or space) is often optional, but can enhance readability for large numbers.

In Britain, standard form is the form called "scientific notation" in the US. Your number would be 6.301005×10³.

It took every 55 minutes to run a 10-meter race last weekend. If you know that 1 kilometer equals 0.621 mile, how many minutes d
Umnica [9.8K]
Velocity=distance/time
Data:distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.time=55 minutes
Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute
Data: distance=1 mile.velocity=0.113 miles/minute
time=distance /velocitytime=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes. 
Answer: D 8.86 minutes.
