3²+b²=5²
9+b²= 25
25-9=16\√
√16=4
(16-10) : 2 =3
h^2+3^2=5^2
h^2+9=25
h^2=25-9
h^2 = 16 | pierwiastkuje
h=4
Wysokość wynosi 4 cm ;)
2)
h^2+3^2=5^2
h^2+9=25
h^2=25-9
h^2=16 | pierwiastkuje
h=4
Wysokośc też wynosi 4 ;P
(16 - 10) / 2 = 3
h^2 + 3^2 = 5^2
h^2 + 9 = 25
h^2 = 25 - 9
h^2 = 16
h = 4
Ad. 2
h^2 + 3^2 = 5^2
(to samo co wyżej)
h = 4
