Answer 1

Explicación paso a paso:

2. Calcula la diagonal de las siguientes figuras, señala si el valor obtenido es racional o  irracional.

a)

Hallamos el diagonal:    

(diagonal)² = a² + b²

(diagonal)² = 8² + 8²

(diagonal)² = 64 + 64

(diagonal)² = 128  

(diagonal) = √128

(diagonal) = 64√2  

b)

Hallamos el diagonal:

(diagonal)² = a² + b²

(diagonal)² = 3/2² + 9²

(diagonal)² = 9/4 + 81

(diagonal)² = 2,25 + 81

(diagonal)² = 83,25  

(diagonal) = √83,25  

c)

(diagonal)² = a² + b²

(diagonal)² = 12,6² + 16,8²

(diagonal)² = 158,76 + 282,24

(diagonal)² = 441  

(diagonal) = √441  

(diagonal) = 21  

d)

(diagonal)² = a² + b²

(diagonal)² = 9² + 12²

(diagonal)² = 81 + 144

(diagonal)² = 225  

(diagonal) = √225  

(diagonal) = 15
