Chapter 12.1, Problem 47WE

To determine

Draw the angle and use a protector to estimate its measure.

Answer to Problem 47WE

  $315°$

Explanation of Solution

Given:

The terminal side of an angle in standard position passes through the given point . $\sqrt{3}=1.73$

  $(4,-4)$

Calculation:

Plot the point $(4,-4)$

and join it to origin .Use a protector to measure the angle :

  

The acute angle is $45°$ . So, the angle in the anticlockwise direction is

  $360°-45°=315°$
