Ответ:
GIVEN: The perimeter of triangle STU is 125.
The segments TW=21 cm
VW=30 cm
VT=24 cm
TO FIND: The length of the segment SU.
SOLUTION:
As corresponding sides must be same. so we have,
Then, TU=7k and TS=8k
As the perimeter of triangle STU is 125.
so,
8·k+7·k+10·k=125
⇒25.k=125
⇒k=5
Therefore, SU=10×5=50

ExplanThe first step in learning about points and miles is to talk about points and miles — and know why using your debit card has no point . . . pun intended. By using a debit card, you’re spending money and not getting anything back in return.
