I want to hang out with my best friend in the morning, but also my other friend wants to come.. My best friend doesn't want her there cause she wants to be alone with me to get bonding time. How do I tell her nicely that she can't come or an excuse not to come?

Like he texted me that he has to get it off his chest and he still likes me. What should I respond? I really don't know how I feel about him.

They're like all confident that you'll like them like this one guy said to me like "Oh I know you love me" & another one said "I know you'll want me to be your man" They said this & I never had any feelings for them & probably never will... Why are guys like this?

So this is the question: the vertices of triangle ABC are A(1,7) B(9,3) C(3,1)

1. Prove ABC is a right triangle.

2. Which angle is the right angle?

3. Which side is the hypotenuse ?

Thanks so much :)

Well this guy commented on my picture: why aren't there girls as pretty as you around where I live? I'm flattered but I don't know what to respond? Advice?

Does anyone know the definition of it? I cant find it anywhere on the internet.

1. In an equalerial triangle, what is the difference between the sum of exterior angles and the sum of the interior angles?

a)180

b)120

c)90

d)60

2. The lengths of the legs of a triangle are 2√5 and 5. What is the length of the hypotenuse?

a) √31

b)√37

c)√43

d)√17

3. Two angles are complementary. One angle has a measure that is 5 times the measure of the other angle. What is the measure in degrees or the large angle?

4. ABCD is a rectangle. AB= 10 BC=4 Find in simplest radical form, the length of diagonal AC.

Please don't just say the answer, explain it too. thank you so much :)

i need like a big purse like preferably big enough for school. online websites are also good :)

Don't answer like "oh cheating is wrong" & **** I really don't care. I usally just look in my bag at the words or just sit on the words & look on my lap. But I need better ways to cheat not to get caught. I never got caught but one of my friends did, so what are some good ways to cheat? (Plus it's like a lot of words 40 I think)

Well I don't really like my school, I'm like the only white person there, I'm very shy person & I didn't make much friends there. How do I transfer out? I'm a freshman right now in NYC.. Is it too late to get an application? Are there any other ways to transfer out?

Do guys find it weird when random girls add them when you don't talk to them? I'm a freshmen & I added this sophomore on Facebook because I thought he was cute & I saw him around the school. Do you think he thinks I'm creepy/weird now because I add him when I don't even talk to him?

like by eye contact & when you see guys in person, how do you know if they find you attractive, cute ect?

I got them for christmas & I love them but idk what to wear with them!

advice ?

He goes to my school & I think he's really cute. I see him around the school & he's in my lunch period. I once caught him and his friends staring at me in lunch lol. Do you think he would get creeped out if we don't talk or anything? Idk I'm really shy in front of guys in general, so do you think this would be a good first step? (We have 5 mutual friends btw lol)

Like i don't even see them at school, or know them or talk to them. Some of my friends know them, but I've never seen them before, but then they add me on Facebook. Why is this ? Lol

We've been only texting for a few days & never really talked in real life (but we're planning to). He keeps being really sweet like sending me pictures that I'm beautiful and stuff, but he like sent me a picture that he loves me and stuff, but we barley know eachother ? What should I respond to this?

what do you respond when a guy tells you he likes talking to you? I think he's kind of cute, but i dont really know him that well soo??
