Hello Kata, how are you? I hope you're doing well. The truth is, I haven't had a good week. I'm actually not okay because it turns out that Maggie isn't the girl she appears to be. Yesterday, we were at her house working on a project, but she wasn't doing anything. When I asked her for help, she told me to do it myself. While I was working on it, she just watched. Honestly, I wasn't surprised by her attitude, but I'm going to tell the teacher about it. The next day, I told the teacher that I did the work myself. But hey Kata, I won't bore you anymore. I wish you a very good week. Many kisses, love.

At the end of the film, Sebastian is able to own his own jazz club, while Mia is living in Paris and starting her acting career. While both of them are making their dreams come true, Mia and Sebastian are following different ways in their lives. When Mia returns to LA, now married to someone we don't know, she and her husband went to Seb’s (Sebastian’s jazz club), where Sebastian is playing. Mia smiles at Sebastian, while contemplating what their life together could have been like. Mia leaves the club, but sharing one last look with Sebastian.

This story is about what happened in a park to me and some friends.

This was a summer night, we were some friends gathered in a park to celebrate some good news, when we were swinging, a very sinister woman appeared, who began to look at us for a long time without moving. Our side, just as we wanted to talk to her, she just smiled at us. So scared we were, we ran away and she immediately began to chase us. When everything was calmer we went to some chairs placed near where we were but the girl reappeared behind us.We, scared to death, wanted to leave and went to a friend’s house to dismiss her so that she would not see us.

The girl never appeared again all night, but when she disappeared, we started hearing screams and asking for help, we stayed... Continue reading "What is the story "what happened to a dean of santiago" about?" »

By the Vertical Angles Congruence Theorem (Theorem 2.6), m∠4 = 115°. Lines a and b are parallel, so you can use the theorems about parallel lines.

m∠4 + (x + 5)° = 180° Consecutive Interior Angles Theorem

115° + (x + 5)° = 180° Substitute 115° for m∠4.
x + 120 = 180 Combine like terms.

x = 60 Subtract 120 from each side.7

By the Alternate Exterior Angles Theorem, m∠8 = 120°.
∠5 and ∠8 are vertical angles. Using the Vertical Angles Congruence Theorem
(Theorem 2.6), m∠5 = 120°.
∠5 and ∠4 are alternate interior angles. By the Alternate Interior Angles Theorem,
∠4 = 120°. So, the three angles that each have a measure of 120° are ∠4, ∠5, and ∠8.

By the Linear Pair Postulate (Postulate 2.8), m∠1 = 180° − 136° = 44°.

The original thirteen colonies were divided into three distinct regions: the New England Colonies, the Middle Colonies, and the Southern Colonies. Each region possessed unique characteristics in terms of their founding principles, challenges faced, religious practices, and economic systems. These differences stemmed from various factors, including interactions with Native American tribes, climate variations, and the motivations behind their establishment. Despite their disparities, all thirteen colonies shared a common thread as English settlements under the rule of the British monarchy.

The New England Colonies

The New England Colonies were renowned for their diversified economy, encompassing fishing, farming, and shipbuilding industries. They... Continue reading "The Thirteen Colonies: A Comparative Analysis" »
