3.Trigonometrical Ratios, Functions and Identities
easy
Find the radian measures corresponding to the following degree measures:
$520^{\circ}$
A
$\frac{26 \pi}{9}$
B
$\frac{26 \pi}{9}$
C
$\frac{26 \pi}{9}$
D
$\frac{26 \pi}{9}$
Solution
We know that $180^{\circ}=\pi$ radian
$\therefore 520^{\circ}=\frac{\pi}{180} \times 520\, radian =\frac{26 \pi}{9} \,radian$
