For this you can work is doing it in a diagram.
Answer:
what
Step-by-step explanation:
A = 3.14 (2)^2
A = 3.14 (4)
A = 12.56
answer
A = 12.56
Answer:
2/4 = 1/2
Step-by-step explanation:
Firstly expand cos(x - 30)....which is..
[cos x.cos 30 + sin x.sin 30]
If sin x = -1/2...then cos x = square root of 3/2
Then substitute the values into the expansion above....which...,
[(square root of 3/2)(square root of 3/2) + (-1/2)(1/2) ]
; 3/4 - 1/4 = 2/4
;Ans = 2/4 = 1/2
