Question

Determine x
Por favor

Answer 1

Boa tarde Maria 

hipotenusa h = m + n = 10

m*10 = 8² = 64
m = 64/10

n*10 = 6² = 36
n = 36/10 

x² = m*n = 64/10*36/10
x = 8*6/10 = 4.8 

Answer 2

Hipotenusa=m+n=10

10m=8²
10m=64
m=64/10
m=6,4

10n=6²
10n=36
n=36/10
n=3,6

h²=m*n
h²=6,4*3,6
h²=23,04
h=√23,04
h=4,8
Resposta: 4,8
