Question

3 tan 45 degree + cos 45 degree - sin 45 degree =?

Answer 1

Answer:

$3 \tan(45) + \cos(45) - \sin(45) = 3 \times 1 + \frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} }$

$3 + \frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} }$

$3$

So, $3 \tan(45) + \cos(45) - \sin(45) = 3$

hope it helps u

:)

for solving this u need to learn the values of these trigonometric ratios...

I have provided them in attachment u may have a look....
