imagine you see an excited crowd of people outside a new spor
de the shop. it's david beckham! you run to get his autoor
someone inside th
you can't. thats because it's not the real david beckham - it's a pro
look-alike
professional look-alikes are people who look like famous stars
they make a living from appearing at parties, events and
sometimes in advertisements. andy harmer is david
beckham's best look alike. he doubles for david beckham on
tv commercials and films. he can also play football well
and he makes appearances with the real david! he looks
so much like the famous footballer that he is a success
wherever he goes. but he doesn't just look like beckham
his voice is similar to david's too.
as david beckham's look-alike, he travels the world and
meets lots of david's fans. andy likes what he does, but it's not
as edsy as it seems. he has to keep fit and copy beckham's new
hairstyles all the time but it's all worth it when the fans see him!

Предположим, что это равносторонний треугольник)
Проводим высоту ВН, так как треугольник равносторонний, то она является и высотой, и биссектрисой, и медианой
В равностороннем треугольнике все углы = 60°
ВН - проекция
Нам известна сторона треугольника АВ = а, тогда ВН=(а×√3)/2
ответ: а√3/2. криво, но как есть
