Proporcion geometrica ​

Answer 1

Respuesta:

c) 4

Explicación paso a paso:

a / b = c / d

ad = bc

abcd = 3600

(bc)² = 3600

bc = √3600

bc = 60

b + c = 16

(b + c)² = (16)²

b² + c² + 2bc = 256

b² + c² + 2(60) = 256

b² + c² + 120 = 256

b² + c² = 256 - 120

b² + c² = 136

b² + c² - 2bc = 136 - 2bc

(b - c)² = 136 - 2(60)

(b - c)² = 136 - 120

(b - c)² = 16

b - c = √16

b - c = 4
