Find the value of sec(theta°)cos(theta°) for the following values of theta.
a. theta = 120

sec(120°)cos(120°) = 1

Step-by-step explanation:

given data

theta = 120

to find out

sec(theta°)cos(theta°)

solution

we have given equation

sec(theta°)cos(theta°)     ......................1

put here value of theta in equation 1

= sec(120°)cos(120°)    ..............2

we know sec(120°) =

so from equation 2

= cos(120°)

= 1

so sec(120°)cos(120°) = 1

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.
