Question

2 tan45 + cos45- sin45=?​

Answer 1

$\huge{\underline{\sf{\red{Answer\leadsto2}}}}$

__________________________________________

Trigonometric Ratios

$\implies$Tan45° =1

$\implies$Cos45° = $\dfrac{1}{\sqrt{2}}$

$\implies$Sin45°= $\dfrac{1}{\sqrt{2}}$

__________________________________________

$2 \times Tan45 + cos45° - sin45$

$\implies$ $2 \times 1 + \cancel\dfrac{1}{\sqrt{2}} - \cancel\dfrac{1}{\sqrt{2}}$

$\implies$ $\large{\boxed{2}}$

Answer 2

Answer:

HEY MATE YOUR ANSWER IS

.

Step-by-step explanation:

2 tan45 + cos45- sin45.

$2 \times 1 + \frac{1}{ \sqrt{2} } - \frac{1}{ \sqrt{2} } \\ = 2 \: ( \frac{1}{ \sqrt{2} } cancel \: out)... \\ hope \: its \: helps...$
