Find the sine and cosine for each angle shown (30°, 45°, 60°, and 90%). Round off to 5 decimal places, if necessary.
sin(30) =
sin(45) =
sin(60°) =
sin(90°) =
cos(30°) =
cos(45°) =
cos(60°) =
cos(90°) =

sin(30) = 1/2

sin(45) = sqrt(2)/2 -> 0.70711

sin(60) = sqrt(3)/2 -> 0.8660

sin(90) = 1

cos(30) = sqrt(3)/2 -> 0.8660

cos(45) = sqrt(2)/2 -> 0.70711

cos(60) = 1/2

cos(90) = 0

Step-by-step explanation:

sin30=1/2=0.5

sin 45=(√2)/2=1.41421356237/2=0.70710678...=0.70711

sin 60=(√3)/2=1.73205080757/2=0.86603

sin 90=0

cos30 =(√3)/2=0.86603

co 45=(√2)/2=0.70711

cos 60=1/2=0.5

cos 90=0

where is the rest of the

step-by-step explanation:

wholesale price is the initial price before markup. retail price comes after the markup.

a price of 8 bucks that's marked up by 100%   is

formula: initial price + (percent markup in fraction/decimal)(initial price)

8+(1)(8)

8+8

16

retail price is $16.
