Question

Determine o valor de x

Answer 1

a)

c² = a × n

(6√5)² = a × 12

36 × 5 = 12a

a = 180 / 12

a = 15

a = m + n

15 = m + 12

m = 3

h² = m × n

h² = 12 × 3

h² = 36

h = 6

a × h = b × c

15 × 6 = x × 6√5

90 = 6√5b

x = 90 / 6√5

x = 3√5

b)

a² = b² + c²

(4√5)² = 4² + n²

n² = 16 × 5 - 16

n² = 64

n = 8

h² = m × n

4² = x × 8

8x = 64

x = 8

c)

h² = m × n

6² = 12 × x

12x = 36

x = 3
