a = 12, b = ?, c = 15
a = ?, b = 7, c = 25
a = 8, b = 15, c = ?
a = 24, b = ?, c = 26

Respuesta :

1: b=9
2: a= 24
3: c=17
4: b=10

Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10
