Get all of your stretching done first before you start singing. Move your neck in slow circles to stretch those muscles, or switch between a big smile and an open mouth in the shape of an 'O' to stretch your face. Do each exercise 5-10 times to stretch your muscles well. Bend your head back and flex your tongue outwards to stretch your throat. Do 5 big yawns to stretch the muscles around your mouth. Focus on one stretch if you don't have much time, or do 5 of each exercise to practice multiple stretches in one sitting. This is when you make your voice imitate the sound of an ambulance's siren, moving up to the higher notes, back down to lower notes, and then back up again in one continuous sound. This will help you find out what your full range is while stretching your vocal cords. These help you reach your maximum high note by trying to imitate the high pitched noise of a siren. Arpeggios are useful exercises that help you transition from the different major and minor scales. Singing arpeggios to different vowels or other sounds is a great way to extend your vocal range. Go online to find videos of arpeggio scales for you to sing along with, helping you practice. You might sing "ee-ee-ee-ee-ee," with the first and last "ee" being the lowest and the middle one being the highest note. Instead of being a continuous sound, arpeggios have very small pauses between each note. Vocal slides are a great way for you to gently reach high notes before coming back down. Use your voice to slide from a low note to a high note, and then back down as if your voice was on a swing. Vocal slides are more controlled than vocal sirens, though they sometimes sound similar. Try humming your vocal slides or choosing a sound like "wooo" or "ahhh." Vocal slides help relax your throat, making it easier for you to reach higher notes. While most of your early practicing should be focused on reaching the high notes briefly and then going back down, after you've mastered this skill, you can go even further. Once you reach your highest note, try to hold it for several seconds before going back down the scale.

One-sentence summary -- Stretch your facial and neck muscles to help your vocal cords. Practice vocal sirens to strengthen your high notes. Try arpeggios to practice your different pitches. Use vocal slides to slowly move up to higher notes. Draw out the high note once you reach it to practice holding it.

Q: Food-themed gift baskets are among the most common, and the traditional wicker basket is an appropriate fit in many cases. If you want to vary from this, however, try to stick baskets or containers that have a comforting, cozy ambiance. For example, you could stack wine and cheese items on a cheeseboard, place gourmet coffees and teas in a burlap gift sack, or arrange fruits and wines in a wooden crate. Knowing that you want to treat the recipient to a basket of delicious food is a good starting point, but "food" is too general to stand as a solid theme. Try to pick a specific type of food or common food pairing and work from there. Popular examples can include: Wine and cheese baskets, containing one or two bottles of wine and several blocks of cheese to accompany the wine; Gourmet tea or coffee baskets, accented with tea biscuits or coffee cake; Chocolate baskets, containing chocolate goodies in multiple forms; Fruit and nut baskets, offering several types of fresh fruit and cans of salted or flavored nuts. Think of the receiver's favorite foods. If the receiver loves chocolate, then some type of chocolate theme is probably a good way to go. On the other hand, that same basket would be a bad choice for someone who lacks a sweet tooth. Consider the time of year. Certain seasons and holidays are associated with different types of food, and you could build a theme around that. For example, autumn is associated with pumpkin, apples, cinnamon, and caramels; winter calls to mind hot chocolate and mint. The exact combination will depend on the theme you choose and your own talents in the kitchen, as well as the amount of time you'll need to wait before delivering the basket. If you plan to present the basket later that same day or the following day, you can probably include more fresh foods like fruits, cheeses, and homemade baked goods. These won't work if you're making the basket a week in advance, though. Opt for preserved foods, commercially prepared foods, or ready-mixes if you need to save the basket for more than a few days. Ready-mixes also work well for recipients who enjoy spending time cooking in the kitchen.
A: Choose a rustic basket option. Narrow down the theme further. Use a combination of fresh foods, ready-mixes, and commercially prepared foods.

Article: The polygon can have any number of sides and can be regular or irregular. For example, you might want to find the sum of the interior angles of a hexagon, so you would draw a six-sided shape. Label this vertex A. A vertex is a point where two sides of a polygon meet. The lines should not cross. You should create a number of triangles. You do not have to draw lines to the adjacent vertices, since they are already connected by a side. For example, for a hexagon you should draw three lines, dividing the shape into 4 triangles. Since there are 180 degrees in a triangle, by multiplying the number of triangles in your polygon by 180, you can find the sum of the interior angles of your polygon. For example, since you divided your hexagon into 4 triangles, you would calculate 4180=720{\displaystyle 4 imes 180=720} to find a total of 720 degrees in the interior of your polygon.
Question: What is a summary of what this article is about?
Draw the polygon whose angles you need to sum. Choose one vertex. Draw a straight line from Point A to each other vertex in the polygon. Multiply the number of triangles you created by 180.
