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.

  • Squared numbers are numbers that are gotten by multiplying a number by itself.
  • For example, square of 25 is 5 (5×5). This means that 25 is a perfect square.

<h3>What is a Factor of a Number?</h3>
