Answer 1

Answer:

5 - $\frac{8}{3}$√3

Step-by-step explanation:

tan 60° = √3

tan 45° = 1

tan 30° = $\frac{\sqrt{3} }{3}$

1). ( √3 - 1 ) ÷ ( √3 + 1 ) = $\frac{4-2\sqrt{3} }{2}$ = 2 - √3

2). ( 1 - $\frac{\sqrt{3} }{3}$ ) ÷ ( 1 + $\frac{\sqrt{3} }{3}$ ) = $\frac{3-\sqrt{3} }{3+\sqrt{3} }$ = $\frac{12-2\sqrt{3} }{6}$ = 2 - $\frac{\sqrt{3} }{3}$

3). ( 2 - √3 )( 2 - $\frac{\sqrt{3} }{3}$ ) = 4 - 2√3 - $\frac{2}{3}$ √3 + 1 = 5 - $\frac{8}{3}$√3
