Answer:

The awnser would be 9 because its under the sum of 10

Answer:

9 (see below)

Step-by-step explanation:

So, for a triangle, if you add any two sides, it will always be greater than the third side.

So if a triangle has sides of 1, 1, and 1:

1 + 1 > 1

1 + 1 > 1

1 + 1 > 1

So this is a triangle.

For a triangle with the sides of 3, 3, and 9:

3 + 9 > 3

9 + 3 > 3

3 + 3 > 9   (this one is not true)

So, these can't be the values of the sides of a triangle.

For your situation, you have a triangle with sides of 4, 6, and x.

We need to find out what x is, so:

4 + 6 > x

4 + x > 6

6 + x > 4

Isolate x to one side and simplify all the inequalities. You will get:

x < 10

x > 2

x > -2

So, -2 < x < 10.

If you plug in your answer choices, it will be 9.

The side lengths of A'A and B'B are 18 and 9 respectively.

What are similar triangles?

When the respective sides are proportional and the corresponding angles are congruent, two triangles are said to be similar.

Given that, segment A'B' is parallel to segment AB.

Let A'A =x and B'B = y.

Since the segments are parallel the triangles ΔA'B'C and ΔABC are similar.

As per the property of similar triangles, it follows:

12/8 = (12 + x)/20

12 + x = (12/8)20

x = 18

And,

6/8 = (6+y)/20

6 + y = (6/8)20

y = 9

Hence, the side lengths of A'A and B'B are 18 and 9 respectively.

She sniffled and used a handkerchief to wipe away her tears. Taking a deep breath, she rapped on the door of the world's most famous detective.Mrs. Hudson answered the door and ushered the visitor to Sherlock Holmes' flat. The detective stood tall and confident, gazing at Mrs. Blakely with an inquisitive smile. He invited Mrs. Blakely to enter. Mrs. Hudson offered her some tea. After using the tea to warm her hands, Mrs. Blakely felt capable of explaining her situation. Yesterday afternoon, Mrs. Blakely had arrived home to find a masked individual robbing her house. When the mysterious figure heard her approach, he or she ran farther into the house and disappeared. All that remained was the black mask lying on the ground. Mrs. Blakely's most prized possession, a massive purple gem, also had disappeared. While Mrs. Blakely knew it would be useless to ask Holmes to retrieve the gem, she wanted him to determine how the thief and gem had disappeared so completely.Sherlock Holmes listened to the tale and agreed to visit the crime scene. The safe was open and empty, but it was not damaged. There was no visible entry into the room where the safe was kept: the windows were sealed, and the door was not damaged. Mrs. Blakely led Sherlock Holmes farther into the house and stopped in the middle of a hallway of old portraits. There were no windows, and the only door was at the other end of the hallway."This spot is where I found the black mask," Mrs. Blakely explained.Sherlock Holmes inspected the hallway with a wrinkled brow. He walked up and down the hallway. He put his hand on the smooth floor. Then, Sherlock's brow smoothed and a glint entered his eyes. Turning to the wall, he pressed the expensive portrait into the wall."What are you doing to my painting?" Mrs. Blakely gasped."Calm down, Mrs. Blakely," Holmes replied. "The solution to this mystery is staring you in the face. There is no sign of a break in, so the thief has access to the house. The thief disappeared in this spot without using the far door, so there must be a hiding spot within the walls or floor. There are scratches on the ground near this portrait. I felt a draft when I reached down to test the floor. It's elementary, Mrs. Blakely. The thief is hidden in the wall behind this portrait."Holmes pushed the portrait harder into the wall. The wall moved, revealing a hiding place. Sherlock Holmes lit a candle. Its light revealed a sleeping maid with a gigantic purple gem clasped in her hands. The mystery of the disappearing thief was solved.Select the detail that supports this statement: Mrs. Blakely was upset when she arrived to speak with Sherlock Holmes.
