I Trigonometry Convert the following degrees to radian measu

I. Trigonometry Convert the following degrees to radian measure. 1. 120° 2. -1750 3. 6850 Convert the following radian measures to degrees. 5 6. 3t 4 4.

Solution

1) 120 degrees to radian

to convert degrees to radian we multiply by pi/180

120 * pi/ 180

= 2.093 radians

2) - 175 degrees

-175 * pi / 180

= - 3.054 radians

3) 685 degrees

= 685 * pi / 180

= 11.96 radians

4) 3pi/4 to degrees

to convert to degree we multiply by 180 / pi

3pi/4 * 180/pi

= 135 degrees

5) 5pi

5pi * 180 / pi

= 900 degrees

6) -5pi/3

= - 5pi/3 * 180 / pi

= - 300 degrees
