-0. 819/root(2)

Answer 2

The value of $\sin 55-\cos 35+\cot 45$ is "1".

Step-by-step explanation:

We have,

$\sin 55-\cos 35+\cot 45$

To find, the value of $\sin 55-\cos 35+\cot 45$ = ?

$=\sin 55-\cos (90-55)+\cot 45$

$=\sin 55-\sin 55+\cot 45$

[∵ $\cos(90-\theta)=\sin\theta$]

$=\cot 45$

= 1

[∵$\cot 45=1$]

Hence, the value of $\sin 55-\cos 35+\cot 45$ is "1".
