=1-(1/√2)^2+(1/√2)^2

=1-1/2+1/2=1 answer

Step-by-step explanation:

=1-(1/√2)^2+(1/√2)^2

=1-1/2+1/2=1 answer

Answer:

1.

Step-by-step explanation:

You can get the values from the 45-45-90 triangle whose side are 1, 1 and √2.

So, sin 45 = 1/√2, cos 45 = 1/√2 and tan 45 = 1,

and tan 45° - sin 45°+ cos 45°

= 1 - 1/√2 + 1/√2

= √2/√2 - 1/√2 + 1/√2

= √2/ √2

= 1.
