Hello!
To convert a degree measure to radian measure, we will need to multiply it by π/180 because one radian is equal to π/180, and exactly 180 degrees.
Given the degree measure of 145, we can multiply it by π/180 and simplify it.
145° × π/180 = 145π/180
145π/180 can be simplified to 29π/36.
Therefore, the radian measure 29π/36 (third choice) is equal to 145 degrees.
Option C: [tex]\dfrac{29\pi}{36}[/tex] is the radian measure of 145 degrees.
Radian is a measure which takes a full circular rotation ( 360 degrees ) as 2π radians.
or symbolically:
[tex]360^{\circ}=2\pi^c \\\\1^{\circ} = (\dfrac{\pi}{180})^{c\\[/tex]
Thus, converting 145 degrees to radian will be as follows:
[tex]1^{\circ} = (\dfrac{\pi}{180})^c\\145^{\circ} = 145 \times (\dfrac{\pi}{180})^c\\\\or\\145^{\circ} = (\dfrac{29\pi}{36})^c[/tex]
Thus, Option C: [tex]\dfrac{29\pi}{36}[/tex] is the radian measure of 145 degrees.
