Answer 1

Answer:

Answer is 1/√3

Step-by-step explanation:

cos^2 30°= (√3/2)^2= 3/4

sin^2 30°= (1/2)^2 = 1/4

1-3/4=1/4 and 1-1/4=3/4

So, √(1/4÷3/4)= √(1/3) = 1/√3... Please mark this Brainliest if it helps

Answer 2

Answer:1/√3 or 3/ √3

Step-by-step explanation:

cos30°=√3 /2 => (cos30)^2 = 3/4

sin30°=1/2. => (sin30)^2 = 1/4

√{1 - (3/4)} /{1 - (1/4)}

= √ (1/4)/ (3/4)

= √ 1/3

= 1 / √3

= √3 / 3. (after rationalisation)
