Answer:
72° = 1.25 radians
Step-by-step explanation:
As we know that,
[tex]1 degree = \frac{\pi}{180} radians[/tex]
Thus, [tex]72^{\circ} = 72\times\frac{\pi}{180}radians[/tex]
⇒ [tex]72^{\circ} =\frac{2\pi}{5}radians[/tex]
⇒ 72° = 1.25 radians {∵ Using π = 22÷ 7 or 3.14}
Both degrees and radians are used to measure the angle. They are units of angle.
