Ответ:

72°

Объяснение:

АОВ=180°-137°=43°

АВО=180°-43°-65°=72°

Поскольку АВД (он же АВО) и АСД (он же угол С) опираются на одну дугу, то они равны. Следовательно С=72°

Glasgow’s manufactures include textiles, food and beverages, tobacco, and chemicals. Engineering and printing are also important in the economy. The city has a number of growing service activities, including telecommunications and software development. Modern business and industrial estates house many small firms, and others have moved to Glasgow’s new towns. Tourism has also increased in importance, aided by the Scottish Exhibition and Conference Centre (opened 1985).

The city is a notable education centre, led by the University of Glasgow (founded 1451). The University of Strathclyde was founded in 1796 as Anderson’s Institution and obtained university status in 1964. Glasgow Caledonian University, founded in 1875, gained university status in 1993. Glasgow’s other postsecondary institutions include the Glasgow College of Nautical Studies, North Glasgow College, and John Wheatley College.

Few ancient buildings have survived the industrial era, apart from the cathedral and Provand’s Lordship (1471), Glasgow’s oldest house, but the historic district known as Glasgow Cross, just east of the modern city centre, preserves buildings and streetscapes from the 17th and 18th centuries and is well endowed with parks and cultural amenities, including the Scottish Opera, the Scottish Ballet, the Royal Scottish National Orchestra, and Kelvingrove Art Gallery and Museum. The Burrell Collection, in Pollok Country Park, includes ancient art and works by European and Asian masters. Glasgow also is the site of the Gallery of Modern Art and the Lighthouse, an exhibition and conference centre devoted to architecture, design, and city planning. The Glasgow Science Centre explores the effect of science and technology on society and includes the Glasgow Tower. This 459-foot- (140-metre-) high tower is the tallest freestanding structure in Scotland and the only structure of its height in the world that revolves 360 degrees from its base. Scotland’s first public museum, the Hunterian (established in 1807), is housed on the grounds of the University of Glasgow.
