Yes, in a right-angled triangle, the hypotenuse is always represented by the letter 'c' in the Pythagorean theorem. The Pythagorean theorem states that in a right-angled triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides. This relationship is always true for any right-angled triangle, making the hypotenuse always represented by 'c' in the theorem. **

The legs of a right-angled triangle are the two sides that form the right angle. The hypotenuse is the side opposite the right angle and is the longest side of the triangle. In a right-angled triangle, the relationship between the lengths of the legs and the hypotenuse is given by the Pythagorean theorem, which states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the two legs. **

In a right triangle, the base is the side that is perpendicular to the vertical height of the triangle. It is the side on which the triangle rests. The hypotenuse is the longest side of the right triangle and is opposite the right angle. It is the side that is directly across from the right angle. **

The median of the hypotenuse in a right-angled triangle is half as long as the hypotenuse itself because it is the line segment that connects the midpoint of the hypotenuse to the right angle. This creates two congruent right-angled triangles, each with half the length of the hypotenuse. Therefore, the median is half the length of the hypotenuse. This property holds true for all right-angled triangles, regardless of the length of their sides. **

In trigonometry, the hypotenuse of a right triangle can be calculated using the Pythagorean theorem. The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the other two sides. So, to find the hypotenuse, you would square the lengths of the two shorter sides, add them together, and then take the square root of the result. This formula can be expressed as c = √(a^2 + b^2), where c is the length of the hypotenuse, and a and b are the lengths of the other two sides. **

To calculate the hypotenuse of a right triangle using square roots, you can use the Pythagorean theorem. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. So, if you have the lengths of the two shorter sides (a and b), you can find the hypotenuse (c) by taking the square root of the sum of the squares of a and b, which can be written as c = √(a^2 + b^2). This formula allows you to find the length of the hypotenuse without needing to measure it directly. **

No, the base of a triangle is not necessarily the hypotenuse. The hypotenuse is the side opposite the right angle in a right-angled triangle, while the base is one of the other two sides. In a right-angled triangle, the base and the hypotenuse are different sides, with the base being the side on which the triangle rests. **

The amount of money that a cinema keeps from the screening of a film can vary depending on various factors such as the popularity of the film, the terms of the distribution deal, and the cinema's operating costs. Typically, cinemas keep a percentage of the ticket sales revenue, with the rest going to the film distributor. This percentage can range from around 50% to 70% for major blockbuster films, with independent and smaller cinemas sometimes negotiating for a higher percentage. Additionally, cinemas also make money from concessions sales, which can further contribute to their overall revenue from screening a film. **
