Question

ayudame porfavor alguien?​

Answer 1

Respuesta:

A x B = 2

Explicación paso a paso:

A = tan²45° + cot²45°

A =  (1/1)² + (1/1)²

A = 1² + 1²

A = 1 + 1

A = 2

----------

B = sen²60° + cos²60°

B = (√3 / 2)² + ( 1 / 2)²

B = (  (√3)(√3) / (2)(2)  ) + (  (1)(1) / (2)(2)  )

B = ( 3 /4 ) + (1 /4)

B = ( 3 + 1)/4

B = 4/4

B = 1

----------

A x B = 2 x 1 = 2
