Question

find the value of sinx if cosx= 1/2​

Answer 1

ANSWER

⇛$cosx = \frac{1(b)}{2(h)}$

Base is 1

hypotenuse is 2

we apply Pythagoras theorem:-

⇛${(H)}^{2} = {B}^{2} + {P}^{2}$

⇛${2}^{2} = {1}^{2} + {P}^{2}$

⇛${P}^{2} = 4 - 1 = 3$

⇛$P = \sqrt{3}$

Now finding sinx

⇛$sinx = \frac{P}{H} = \frac{ \sqrt{3} }{2}$

Answer 2

Answer:

√3/2

Step-by-step explanation:

sinx=1/2

therefore sin60=1/2

x=60°

cosx=?

cos60=√3/2.
