Question

If tan 45 is equal to 1 what is the value of sin 45 + cos 45​

Answer 1

Answer:
`\sqrt2` or 1.41

Answer 2

If tan(45)=1
And we know that tan=sin/cos
We need to change sin(45) +cos(45) to be sin(45)/cos(45) = 1
Or you could find the value if sin(45) which is = 0,7071067812 and cos(45)=0,7071067812 and when you divide the values of sin and cos your answer is 1
