Question

Calcule o valor de x nos triângulos retângulos

Answer 1

a
cateto b = x
m = 9
a = 25
b² = am
x² = 25 * 9
x² =225
Vx² = V225
x = 15 ***
b
a = 9
cateto c = x
n = 5
c² = an
x² = 9 * 5
x² = 45
Vx²  = V45 = V(3² .5)
x = 3 V5 ***

c
cateto b = 3
cateto c = 4
a =  5
h = x

bc = ah
3 * 4 = 5x
5x = 12
x = 12/5 =2,4 ****

d

m = 4
n = 16
h = x
h² = mn
x² = 16  * 4
x² = 64
Vx² = V64
x = 8 ****
