Twierdzenie piagorasa
a) 12²+x²=20²
144+x²=400
x²= 256
x= 16
b) x²+21²=29²
x²+441=841
x²=400
x=20
c) 8²+x²=17²
64+x²= 289
x²= 225
x= 15
a)
Twierdzenie Pitagorasa:
a² + b² = c²
12² + b² = 20²
144 + b² = 400
b² = 400 - 144
b² = 256
b = √256
b = 16
b)
21² + b² = 29²
441 + b² = 841
b² = 841 - 441
b² = 400
b = √400
b = 20
c)
8² + b² = 17²
64 + b² = 289
b² = 289 - 64
b² = 225
b = √225
b = 15
