Answer 1

Respuesta:

a.

a^2 + b^2 = c^2

a = 3cm

b = 4cm

c = x

3^2 + 4^2 = x^2

9 + 16 = x^2

25 = x^2

√25 = x

5cm = x

x = 5cm

b.

AB = 12cm

AC = 13cm

CB = y

AB^2 + CB^2 = AC^2

12^2 + y^2 = 13^2

144 + y^2 = 169

y^2 = 169 - 144

y^2 = 25

y = √25

y = 5

Ahora:

CD = 3cm

CB = 5cm

BD = x

CD^2 + BD^2 = CB^2

3^2 + x^2 = 5^2

9 + x^2 = 25

x^2 = 25 - 9

x^2 = 16

x = √16

x = 4cm
