Trapetsiyaning bitta asosi ikkinchisidan 8sm ga uzun, o'rta chizig'i esa 10sm ga teng. Trapetsiyaning kichik asosini toping. Shuni qanday ishlaydiOsonku! Kichik asos- a deb belgilaymiz. Katta asos shartga köra a+8 ga teng. Örta chiziq esa formulaga köra kichik asosga katta asosni yig'indisini qöwib 2ga bölinganiga teng yani (a+b):2. Endi biz buni (a+a+8):2=10 deb olamiz
2a+8=20 => 2a=12 => a=6
Javob: kichik asos - 6, kattasi - 14
