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
The answer is 35
i know this because the side is 5 and the other side is 7
so if you multiply 5 time 7 it will equal 35

Answer:
$147.25
Step-by-step explanation:
The hat shop wants to markup the hat that they bought for $95 by 55%.
This means that they want to increase the price by 1.55 of 95.
Multiply 95 by 1.55 to calculate the 55% increase of the hat.
The selling price of the hat should be $147.25.
