Use inverse trigonometric functions to solve each problem.

The angle of elevation for this example is  θ  =  30.96 o

Step-by-step explanation:

For this situation we will use the Tangent function of

tan  θ  =  o p p/ a d j

tan θ  =  30 50  

tan − 1 ( .60 ) = θ

0 =   30.96 o  

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.

2/3x + 7 = 29

step-by-step explanation:

two thirds = 2/3

plus a number = x

at least 29 = 29

there for you should get 2/3x + 7 = 29
