Объяснение:

Найдем угол АВС=180-150=30°. Так как меньший катет лежит напротив 30°, значит он равен половине гипатинузы.

Пусть АС х см, тогда АВ 2х см

х+2х=15

3х= 15

х=5

АС 5 см

They missed breakfast and Savvas was late so James and Bruce stopped off for an early lunch at a Pizza Hut buffet. Chloe had arranged it so that she bumped into them. She gave James a replacement phone and said that another stab-proof sweatshirt was being made on campus and would be ready within forty-eight hours. She also told the boys that she was worried: the ethics committee weren’t going to like it when they heard about the latest outbreak of violence and the death of Julian Pogue. There was a chance they’d pull the mission.

James over-ate and felt bloated as they rode the bus out of Luton and into neighbouring Dunstable. The Rudge Estate consisted of three-storey blocks. Quite a few flats had been purchased and renovated by residents complete with window boxes and neat gardens, but much of the estate was still a dump, strewn with rubbish, graffiti and the occasional abandoned car.
The hard front faced on to a second-floor balcony, but it was far from the only apartment with a reinforced door and bars up the windows, so only a nosy neighbour would have figured it was being used by drug dealers.
The blocks ran parallel to one another. James and Bruce had the keys to a second-floor flat in the next block along, with the front window directly overlooking the hard front. The previous resident’s kids had drawn all over the walls, but nobody had lived there in a while and the musk of damp and dust knocked Bruce back as he pushed the door open.
‘What a pen and ink,’ James complained, wafting a hand in front of his face as he kicked the door shut and dumped the large sports bag that Savvas had given him on the hallway carpet. ‘Better open the windows to air it out.’
It was the middle of the day, but James flipped the light switch on and off to make sure the electricity was connected as Bruce walked between rooms, opening windows.
‘There’s a kettle and a fridge in here,’ Bruce yelled. ‘Maybe we can get some tea and milk in or something.’
‘If you like,’ James shrugged. ‘I guess it’ll take a while going through the tapes, but I don’t fancy spending any longer than I have to in this dump.’
‘It’ll be OK
