Answer:

First Drop: Proportional

Second Drop: cf

Third Drop: [I think] Segment Addition Postulate

Step-by-step explanation:

I just looked through several websites with the same question. I have come to a conclusion that these are perhaps correct. (I'm taking the test right now)

Answer:

1. Proportional.

2. ce

3. Segment Addition Postulate.

Step-by-step explanation:

By the angle-angle similarity postulate, △YXZ∼△YZQ and △YXZ∼△ZXQ.

The corresponding sides of two similar triangles are proportional.

Since similar triangles have  proportional sides, therefore

\frac{a}{c}=\frac{f}{a} and \frac{b}{c}=\frac{e}{b}

Solving the equation for a² and b² gives

a^2=cf and b^2=ce

The value of a² is cf and the value b² is ce.

Adding these together gives

a^2+b^2=cf+ce

Factoring out the common segment gives

a^2+b^2=c(f+e)

From the given figure it is clear that

c=f+e         (Segment Addition Postulate)

Using segment Addition Postulate, we get

a^2+b^2=c(c)

On simplification, we get

a^2+b^2=c^2

Therefore the required answers are 1. Proportional, 2. ce, 3. Segment Addition Postulate.

Judd worked 40 hours this week. He worked 7/10 of the hours outside and the rest inside. How many hours did he work outside?
Mnenie [13.5K]
If you would like to know how many hours did Judd work outside, you can calculate this using the following steps:

40 hours
outside: 7/10 of the hours = 7/10 * 40 hours = 7/10 * 40 = 28 hours

Judd worked 28 hours outside.

I need the steps to this problem, please!

Hello Ashley!

This is an isosceles triangle. How do we know? Well, the two little bar they put means that it is isosceles. When you add all the angles together, you MUST find them equal to 180. Another you need to keep in mind is that the angle that are face to face with each other are ALWAYS equal.

Too much talking...we gonna solve the problem.

x + x + 72 = 180
2x + 72 = 180
2x = 180 - 72
2x = 108
x = 108/2
x= 54
That's the answer .

---------------------
What did we say earlier? We said that when we add all the angles together we MUST find them equal to 180. So, we gonna replace x by 54

54 + 54 + 72  = 180
180 = 180
So.. yes we got it right!

54 is the correct answer.

Good luck with your studies!
