Answer 1

Answer:

option B is correct...

Answer 2

Answer:

(C) is the answer on the task

Step-by-step explanation:

tan 30° = $\frac{\sqrt{3} }{3}$

tan 45° = 1

tan 60° = √3

$\frac{\sqrt{3} }{3}$ × $\frac{3}{\sqrt{3} }$ = 1

d = $\frac{3}{\sqrt{3} }$ = √3

Statement A is true

( sin β + cos β )² + ( sin β - cos β )² = 1

L.H.S.

sin² β + 2(sin β)(cos β) + cos² β + sin² β - 2(sin β)(cos β) + cos² β =

2sin² β + 2cos² β = 2(sin² β + cos² β) = 2

L.H.S. ≠ R.H.S. ⇒ Statement B is false.

(C) is the answer on the task
