Question

me ajudem por favor!!!!​

Answer 1

1.

x² = 12² + 16²

x² = 144 + 256

x² = 400

x = √400

x = 20 cm

2.

10² = x² + 6²

100 = x² + 36

x² = 100 - 36

x² = 64

x = √64

x = 8 cm

3.

15² = x² + 9²

225 = x² + 81

x² = 225 - 81

x² = 144

x = √144

x = 12 cm

4.

13² = x² + 5²

169 = x² + 25

x² = 169 - 25

x² = 144

x = √144

x = 12 m
