natka813 [3]

Answer:

38.3%

Step-by-step explanation:

Discount = Original Price x Discount %/100

Discount = 28.99 × 38.3/100

Discount = 28.99 x 0.38299999999999995

You save = $11.10

Final Price = Original Price - Discount

Final Price = 28.99 - 11.10317

Final Price = $17.89

Discount = 38.3%

Find the measure of the indicated angle to the nearest degree.
azamat

Step-by-step explanation:

Let the measure of required angle be x degree

\therefore \tan \: x =  \frac{45}{28}  \\  \\ \therefore \tan \: x =  1.60714286  \\  \\ \therefore  \: x =   {\tan}^{ - 1} (1.60714286)  \\  \\  \therefore  \: x =   {\tan}^{ - 1} ( \tan \: 58.109 \degree) \\  \\    \huge \red{ \boxed{\therefore  \: x =   58\degree}}

Thus, first option is the correct answer.
