DBE is similar to ABC by the SAS Similarity Theorem

Answer:

Step-by-step explanation:

In the given figure we have two triangles (One into another).

In triangle BDE,

DB=10\ cm

BE=16\ cm

In triangle ABC,

AB=BD+AD=10+15=25\ cm

BC=CE+EB=24+16=40\ cm

Now, in ΔABC and ΔBDE , we have

\angle{B}=\angle {B}                [Reflexive property]

\dfrac{BD}{AB}=\dfrac{10}{25}=\dfrac{2}{5}=\dfrac{16}{40}=\dfrac{BE}{CE}

By SAS Similarity Theorem ​,

ΔDBE ​ is similar to ​ ΔABC ​

  • SAS Similarity Theorem say that if two sides in a triangle are proportional to two sides in another triangle and the included angle in both are congruent then the two triangles are said to be  similar.

cassidy loves black and yellow jelly beans she noticed when she was counting them that she had 7 less than three times as many b
Dmitriy789 [7]
Most of the information's are already given in the question. It is important to understand the language of the problem for solving the problem. Once the language is understood, then solving the problem is easy.
Let us assume the number of black jelly beans = x
Number of yellow jelly beans = y
Then from the question we can get to a equation.
3x - 7 = y
We also know from the question that
x + y = 225
x + 3x -7 = 225
4x = 225 + 7
4x = 232
x = 232/4
   = 58
So Cassidy has 58 black jelly beans out of the total of 225 jelly beans

A small town's phone numbers either begin 373 or 377. How many phone numbers are available?
ser-zykov [4K]

Answer:

  • <u><em>There are 20,000 number available.</em></u>

Explanation:

To determine <em>how many phone numbers are available </em>you need to know how many digits the number contains.

I will assume the same number of digits for other similar questions, i.e. 7.

With 7 digits, the numbers that begin with 373 or 377 can be of the form 373XXXX or 377XXXX.

Where each X can be any digit 0 - 9. Then, there are 10 different options for each X.

Thus, there are 10×10×10×10 = 10,000 different numbers starting with 373 and other 10,000 different numbers starting with 377.

In total, there are 20,000 numbers available.
