Answer 1

Step-by-step explanation:

Here is your answer....

Answer 2

${\huge{\underline{\underline{\green{\bf{Answer}}}}}}$

$➜ 2tan²45º + cos²30° – sin²60°$

$➜ 2({1})^{2} + ( { \frac{ \sqrt{3} }{2} })^{2} - ( { \frac{ \sqrt{3} }{2} })^{2}$

$➜ 2(1) + \frac{3}{4} - \frac{3}{4}$

$➜2 + 0$

$➜2$

${\bold{\underline{\underline{\sf{2 tan²45º + cos²30° – sin²60° = 2}}}}}$
