Question

Calcule o valor de X nos triângulos retângulos:

Answer 1

Resposta passo a passo:

a)

h² = n.m

x² = 9 . 16

x² = 144

x = √144

x = √12²

x = 12

b)

b² = c.n

3² = 5x

9 = 5x

x = 9/5

c)

a² = c.m

4² = 5x

16 = 5x

x = 16/5

d)

a² = c.m

20² = 25m

400 = 25m

m = 400/25

m = 16

h² = m.n

12² = 16n

144 = 16n

n = 144/16

n = 9

b = √(c.n)

x = √(25 . 9)

x = √225

x = √15²

x = 15

e)

h² = n.m

8² = 4x

64 = 4x

x = 64/4

x = 16

f)

a² = m.c

20² = 16x

400 = 16x

x = 400/16

x = 25
