Question

please answer quick​

Answer 1

Answer

1

Step-by-step explanation:

tan(theeta)=1/root3

tan(60)=1/root3

theeta=60

sin60=root3/2

cos60=1/2

(root3/2)^2 + (1/2)^2

3/4 + 1/4 = 1

Answer 2

Step-by-step explanation:

Hi friend!!!

√(3) tan θ = 1

tan θ = 1/√(3)

So, by trigonometric ratios, θ = 30°

sin^2 30 - cos^2 30 = (1/2) ^ 2 - (√(3)/2)^2

                                 = 1/4 - 3/4

                                 = -2/4 = -1/2

Hope it helps!!!!
