Используем теорему синусов:

AB : AC = sin C : sin B

AB = AC · sin C : sin B = 33 · 0,5√3 : 0,5√2 = 33√(3/2) ≈ 40,4

Ответ: АВ = 40,4 см

The interior of the home refers to all the finished surfaces on the interior walls, ceilings and floors as well as such components as doors, windows and stairs. The finished interior of a home includes the internal structure and systems (plumbing and electrical) and should be designed to provide a certain level of comfort and aesthetic enjoyment. Here we are going to speak about floors. A floor is the walking surface of a room. Floors vary from simple dirt in a cave to many-layered surfaces using modern technology. Floors typically consist of a subfloor for support and a floor covering. In modern buildings the subfloor often has electrical wiring, plumbing, and other services built in. The floor covering is any finishing material applied over a floor structure to provide a good walking surface. Different materials can be used as the floor covering. It may be stone, wood, bamboo, metal, or any other material that can hold a person’s weight. Using of the material depends on a place where it will be installed. Every kind of material has its advantages and disadvantages. For example: Hardwood floors are very common in today’s market. The most commonly used wood is oak. It is usually identified by its hardness. The material can be easily installed, sanded, stained and finished. Parquet floors are usually high quality floors. The most common problem with this flooring is that the adhesive becomes loose. You can usually sense loose flooring when you walk over the loose area. Floors tend to loosen with moisture or conditions with high relative humidity, and in high traffic areas. This kind of floors has a “V” joint between the pieces, which makes re-finishing difficult. This joint collects dirt and greases over the years, which makes cleaning and preparing the floor tedious. Vinyl goods are dependable, as long as the installation is performed properly. There is a wide range in quality. Loose tiles are often a sign of moisture or workmanship concerns, particularly in the kitchen and basement areas. Floor vibration is a problem with floors. Wood floors tend to pass sound, particularly heavy footsteps and low bass frequencies. Floating floors can reduce this problem. Concrete floors are usually so massive they do not have this problem, but they are also much more expensive to construct and must meet more stringent building requirements due to their weight. Floor cleaning is a major occupation throughout the world. Cleaning is essential to remove dirt. Floors are also treated to protect or beautify the surface. The correct method to clean one type of floor can often damage another, so it is important to use the correct treatment.
