Climbing in the
Tien Shan Mountains
Do you like mountaineering? The
Tien Shan is the largest mountain
range in Central Asia and attracts
thousands of climbers every year.
Only experienced climbers can go
up the Khan Tengri, which is the
highest peak in Kazakhstan, but
trekking is suitable for everyone.
Позвольте рассуждать так:
а) т.к. треугольники подобны, то численно отношение подобных сторон будет выражаться одним числом(цифрой)
б) пусть АB/MN = x/y
в) но тогда и отношение BC/NP=x/y
г) получили: (АB/MN)·(BC/NP)=x²/y² т.е x²/y²=4 или x/y=2
д) Вы уже, конечно, увидели, что это означает, что все подобные стороны одного треугольника в 2 раза больше, соответствующих подобных сторон другого треугольника
е) поэтому крайнюю дробь в условии задания , можем переписать как: (AB+BC+AC)/(MN+NP+MP)⇒ (AB+BC+AC)/(0,5AB+0,5BC+0,5AC)⇒
(AB+BC+AC)/0,5·(AB+BC+AC)⇒2·(AB+BC+AC)/(AB+BC+AC)=2
