Ответ:

71°

Пошаговое объяснение:

1. ∠CBA равен разности 180° и 156° ⇒ ∠CBA = 180° - 156° = 24°

2. По определению треугольника сумма внутренних углов равна 180°. Следовательно ∠x = 180° - (85° + 24°) = 71°

The air is heavy with the smell
of gunpowder, and there
are blood-stained bodies all
around me. Suddenly, I hear
the tremendous ‘boom’ of
a cannon, and smoke fills my
eyes. In the distance I can just
see a soldier on horseback –
and he’s coming right for me.
My heart is beating like a drum, and I’ve never
felt so afraid …
Fortunately, of course, the blood I can see is all
make-up, and this battle is not for real. I’ve come
here to experience a historical re-enactment
of the English Civil War. Role play enthusiast
Simon Lowe has agreed to be my guide for the
day. He’s brought me a spare costume – short
wool trousers, a cotton shirt, a leather tunic
and a musket, which is the kind of gun they
used in the 17th century. We certainly look like
characters in a film.
This is quite an unusual way to spend the
weekend, so I’m keen to ask Simon how he
got involved. ‘I’ve always been interested in history,’ he told me. ‘When
I was young, my parents took
me to the re-enactment of
a Viking battle, and it was
amazing – really dramatic!
It’s just something that I’ve
always wanted to do. And I’ve
met some great people here
– including my girlfriend.’
After the battle, Simon
introduces me to some other members of the group.
On Monday morning they’ll be back in the office or in the classroom, but for now they’re
enjoying their lives as 17th century soldiers and peasants. When the time comes for me to
say goodbye and step back into the modern world, I feel quite sad. I’ve had a great time,
and I’ve learnt more about history than I ever would in a textbook!
