This is fairly simple. You would just substitute the answer choices in for 'n'.
3^-243=0
So, A. isn't correct.
3^-27=1.31137265.....
So, B. isn't correct.
3^-4=0.123456789 In fraction form this is 1/81
So, we think C. is the correct answer, but just to be sure,  let's try D.
3^4=81 In fraction form this would be 81/1.
So, C. is our answer. 
Hope this helps!!

If 1-cosA = 1/2 , Then find the value of sinA.
zimovet [89]

Step-by-step explanation:

Given :

1- cosA = 1/2

or, CosA = 1 -1/2

Therefore ; CosA = 1/2 = b/h

According to the Pythagoras theorem,

P = root under h^2 - b^2

= root under (2)^2 - (1)^2

= root under 4 -1

= root 3

Again,

SinA = P/h

= root 3 / 2
