how many triangles can you make with two side lengths of 6 inches that meet at a 50 degree angle.

Answers

Answer: Exactly One Triangle

======================================================

Explanation:

Recall that by the SAS (side angle side) congruence theorem, if we know that two pairs of sides are the same length and the angles between them are also congruent, then we can conclude the triangles are congruent. This further means that we can only construct exactly one triangle with two side lengths of 6 inches, and they form a 50 degree angle between them. Applying transformations such as rotations, translations, or reflections will not change the triangle.

Side note: This triangle is isosceles because two sides are the same length. It is not equilateral because we would need to have all three angles to be 60 degrees.

Answer:

One triangle only

The net of a square pyramid is shown below. What are the possible areas for a single face in this net? Check all that apply.

A net with a square base with sides lengths of 5 meters, and 4 triangles with heights of 6 meters.
11 square meters
15 square meters
24 square meters
25 square meters
30 square meters

Answers

Answer: 1,2,and 4. I did it online and got it right!

Answer:

B. 15 square meters (for the triangles)

D. 25 square meters (for the square base)

Bonus: The total surface area would be 85 square meters.

Step-by-step explanation:

The square base is easier to deduce here; simply square 5 to get 25 square meters for the base.

The triangles require some math, however. But it is relatively simple

(5 * 6)/2

30/2

15 square meters for the triangles.

For bonus, I'll find the total surface area.

5² + 4((5 * 6)/2)

First, square 5 to get 25.

25 + 4((5 * 6)/2)

Now multiply 5 * 6 to get 30.

25 + 4(30/2)

Then divide 30 by 2 to get 15.

25 + 4(15)

Now multiply 4 by 15 to get 60.

25 + 60

Lastly, add 25 and 60 to get 85.

The entire square pyramid's surface area is 85 square meters.

I hope this helps! ヽ(*⌒▽⌒*)ﾉ

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?

Answers

Answer:

x = 7

Step-by-step explanation:

The 2 angles are adjacent and sum to 180° , that is

11x + 8 + 12x + 11 = 180

23x + 19 = 180 ( subtract 19 from both sides )

23x = 161 ( divide both sides by 23 )

x = 7

Written by Katie Thompson-Chapter 3By the time we have managed to pull the now snoring unicorn out onto the driveway, the color in Joes face completely gone. HowWhereDid this thing come from? he asks, panting.What, afraid its real after all? I ask.He looks up at me and offers a half-smile. Who wants unicorns to be real if they look like that?I hide a laugh. WellNow we just have to figure out how to wake it up. I poke it a few times with my foot, trying to keep some distance. It just keeps snoring.Joe shrugs and bends down next to its ugly face and starts jiggling its shoulder, like hes trying to wake up a very old uncle.Suddenly its eyes open wide, and with an unbelievable grace, it stands upright. Joe jumps away to give it space, and I just keep staring at it. It walks over to the desert-style landscaping of my neighbors side yard and being perusing for its breakfast.That things a lot more agile than I imagined it would be, Joe says. We both stare at it as it saunters around, pulling up the grassy weeds from between the rock mulch. Sothats a unicorn.I look up at Joe and he's got this silly grin on his face. It's just so 'Joe' that I giggle. Do you believe that's what it is yet? I ask.I could if I wanted to, he replied.I looked up at him, questioning.That thing, he points to the unicorn. I could believe it was if I wanted to.The unicorn seems to have decided that it isnt going to find anything worth eating here and starts to walk down the sloping back yard to the next street. It looks almost like it belongs there, like a stray deer who often grazes around this part of town when no person is awake or watching. When it disappears from our sight, I feel like a ton of responsibility has been lifted from me.The whole morning seems almost trivial. Well, I say, I guess that is that?Joe shrugs, checks his watch, and motions toward the bus stop. We should get going, he says. I grab my bag, and we walk down the driveway.I don't know if that thing was a unicorn or not, he says, looking up into the sky like he might see a dragon flying around to confirm my claim. But I'm glad you called me this morning.Sorry I wasnot very nice, I say, hesitating.He laughs a little but keeps looking around. Then with a huge gulp of air, Do you believe we could be friends again? Like, real friends again? Because I gotta say, I really do miss you, Anna.I smile, remembering what he said earlier and reply, I believe we could if we wanted to.This time he looks over at me. And?And I really hope we want to.What is the main problem in this chapter of the story?a) Joe is completely uninterested in being friends with Anna again, but won't say why.b) When Joe asks Anna to be his friend, she becomes even more uncomfortable and says no. c) Even though she feels a little better, Anna still isn't sure what Joe is thinking about their friendship.d) The sleeping unicorn is very angry when it wakes up, and it starts ruining the neighbor's yard. please please help me I will mark brainlist !! a bag contains 1 red beads,2 yellow beads,2 green beads and 1 blue beadsa bead is chosen at randoma)what is probability that it is green ?b)what probability that it is green or yellow Sustainability means that the needs of which two populations will be met.Present and future humansPast and future humansAmericans and non-AmericansPolar Bears and Rainforest animals Which caused the US Army to take over the atomic research project being conducted at Columbia University in the early 1940s? the first atomic bomb test a letter from Albert Einstein Japan's research into atomic bombs the US entry into World War II Pls help I dont know hot to multiply the last part 8 2 Rachel received a monthly raise of $105.25.

The authors of a paper concluded that more boys than girls listen to music at high volumes. This conclusion was based on data from independent random samples of 768 boys and 745 girls from a country, age 12 to 19. Of the boys, 397 reported that they almost always listen to music at a high volume setting. Of the girls, 331 reported listening to music at a high volume setting.Do the sample data support the authors' conclusion that the proportion of the country's boys who listen to music at high volume is greater than this proportion for the country's girls? Test the relevant hypotheses using a 0.01 significance level. (Use a statistical computer package to calculate the P-value. Use boys girls. Round your test statistic to two decimal places and your P-value to four decimal places.)
