Answer 1

Step-by-step explanation:

hey here is your answer

Answer 2

Answer:

3

Step-by-step explanation:

$2tan^{2} x=(tanx)^{2} \\sin^{2} x=(sinx)^{2}\\cos^{2} x=(cosx)^{2}$

$tan45=1\\cos60=\frac{1}{2} \\sin60=\frac{\sqrt{3}}{2}$

$2*1^{2} +(\frac{1}{2})^{2} + (\frac{\sqrt{3} }{2})^{2} \\=2+\frac{1+3}{4} \\=3$
