Da, takoi treugolnik sushestvuet.
Davayte oboznachim storony treugolnika kak a (samyi korotkii storony), a + 4 (sgushchennyi), a + 1 (srednii), gde a - 4 = samyi korotkii storony.
Postroim vyrazheniia na osnove dannykh:
a + a + 4 + a + 1 = 143a + 5 = 143a = 9a = 3
Sledovatel'no, storony treugolnika budut 3 DM, 7 DM i 4 DM.
Proverim summu dlin storon:3 + 7 + 4 = 14
Treugolnik s takimi storonami sushestvuet.
