Question

If 2 sin 0-1 = 0, find :
(i) the value of 0 in degrees, where 0 is an acute
angle ;
(ii) cos²0 + tan²0​

Answer 1

Answer:

I hope this helps you

Step-by-step explanation:

i think 60 degreee

Answer 2

Answer:

Step-by-step explanation:

Given : 2 sinA - 1 = 0.

⇒ 2 sin A = 1

⇒ sin A = 1/2

⇒ sin A = sin 30

⇒ A = 30.

Here, A is an acute angle.

Now,

(ii)

⇒ Sin A = sin 30

            = 1/2.

(iii)

⇒ Tan A = Tan 30

               = 1/√3.

⇒  cos A = cos 30

              = √3/2.
