Answer:

A. (AB/BC)=(CE/ED)

Step-by-step explanation:

Property of similar triangles :

If two triangles are similar then the corresponding sides are in same proportion,

Here, \triangle ABC\sim \triangle CED

By the above property,

\frac{AB}{BC}=\frac{CE}{ED}

Hence, the column prove would be,

            Statements                      Reason

1. AC ⊥ CD

Δ ABC is similar to ΔCED                         Given

2. (AB/BC)=(CE/ED)                          Property of similar triangle

3. Slope of AC = -AB/BC                    Definition of slope

Slope of CD = ED/CE

4. Slope of AC  × Slope of CD           Multiplying the slopes

= -AB/BC × ED/CE

5. Slope of AC  × Slope of CD           Substitution property of equality

= -CE/ED × ED/CE

6. Slope of AC  × Slope of CD = -1   Simplifying the right side.

Hence, option 'A' is correct.

Answer:

A.(AB/BC)=(CE/ED)

Step-by-step explanation:

Properties of Similar Triangles  states two things

Corresponding angles are congruent (same measure)

Corresponding sides are all in the same proportion

That means AB/ BC = CE/ED

A Genesse High School, the Sophomore class has 60 more students than the Freshmen class. The junior class has 50 fewer students
alexira [117]
1427 = (F) (+ F + 60) (2F - 50) (+ 3F)
<em>Each pair of brackets represents one of the classes - F meaning Freshmen Class. It has been split into brackets for demonstrational purposes - nothing is being multiplied.</em>
F is an unknown number and each other class size is based off of that so we put it in algebraic terms in order to work it out.
1 - Freshmen Class
2 - Sophomore Class (Freshmen Class + 60 more students)
3 - Junior Class ( Twice the size of the Freshmen Class - 50 students)
4 - Senior Class (Three times the size of the Freshmen Class)

All this can be simplified to 7F + 10 = 1427
1427 - 10 = 1417
1417/7 = 202.428....

Is there a mistake in the question?

Following the question with 202 as the answer - the number 1424 is reached
If increased to 203 - 1431 is reached.
The answer shouldn't include half a person.

What is the solution to the equation 3x-5=2x+8+x?
Marysya12 [62]
So when solving this you are going to have to solve the equation.
Okay so first thing we need to do is simplify both sides of your equation so:
3x−5=<span>2x+8+x
</span>Simplifying process:
<span><span><span>3x</span>+</span>−5</span>=<span><span><span>2x</span>+8</span>+<span>x
</span></span><span>Combine Like Terms </span>⇒ 3x−5=<span>(2x+x)+(8)
</span><span><span>3x</span>−5</span>=<span><span>3x</span>+<span>8
</span></span><span><span>3x</span>−5</span>=<span><span>3x</span>+<span>8
</span></span>Second thing we are now going to do is s<span>ubtract 3x from both sides<span> so:
</span></span><span><span><span>3x</span>−5</span>−<span>3x</span></span>=<span><span><span>3x</span>+8</span>−<span>3<span>x
</span></span></span><span>−5</span>=<span>8
</span>Final step is to add 5 to both sides:
−5+5=<span>8+5
</span>0=<span>13
</span>The answer to your question is "<span>There are no solutions"</span>
